Yorkshireman likes to be complimented on his foresight and good
sense by an acknowledged expert.
“I wonder if he would paint my wife,” said Mr. Crosby of the Foreign
Office.
“You can ask him, my dear fellow,” said the expert.
“Would he want a stiff figure?” said Mr. Crosby, who had a very
practical mind.
“It would cost you a cool thousand, I dare say,” said Cheriton, before
Kendal could announce that it had cost him five hundred.
“Stiff, ain’t it, for an unknown man?” said Mr. Crosby.
“He is going to be the man, my dear fellow,” said Cheriton. “What do
you say, Caroline? You have seen some of his work.”
“I agree with you, Cheriton,” said the flattered Caroline, who knew as
much about pictures as Ponto did. “He has painted two of my nieces,
and in my opinion they are excellent likenesses.”
“Have you two nieces, Caroline?” said the Marquis. “That is
interesting. When are we to have the opportunity of seeing the other
one?”
“Next season—perhaps.”
As yet there had been no formal announcement of Cheriton’s
engagement, but it was known to many. It is true that those who
were best acquainted with him maintained an attitude of incredulity.
So many times in the past had there been talk of entertaining at
Cheriton House. Yet there was a consensus of opinion that he really
meant to settle down at last; and while all disinterested people could
not fail to admire his taste, the critical were a little inclined to doubt
his wisdom. Still, there was no doubt about the beauty and the
docility of his choice, and in her quaint way she had unmistakably
the bel air. She was a good honest girl, a Wargrave, and the old
woman of Hill Street could well afford to do something in the matter.
Still, the knowing ones “could not see it at all”; those who were not
so knowing thought that “Cheriton might have done worse.”
All the same, Miss Perry was famous and she was popular. Her
simplicity was something that was growing very rare; she was
unaffectedly good to everybody, and everybody could not help being
grateful to her for her goodness, because it sprang straight from the
heart. No matter whether people were important or unimportant, it
made no difference to her. Great beauty and an absolute friendliness
which is extended to all, which keeps the same gracious smile for
the odd man about the stables that it has for the wearer of the
Garter, will go far towards the conquest of the world.
Miss Perry had conquered her world. All agreed that Cheriton had
done well. Yet the creature was not in the least happy. So much
practice, however, had the Wargraves had in the course of the
centuries in dissembling their unhappiness and in offering their
heads to the block, that only four persons were able to suspect that a
brave, smiling, and bountiful exterior concealed a broken heart.
Jim Lascelles was one. He knew for certain. Miss Burden was
another. Caroline Crewkerne was no believer in broken hearts. For
one thing, she had never had a heart of any sort to break. But she
had seen those great damp splotches on the correspondence with
her father, she had noticed that the creature’s appetite was not what
it was; and there were half a dozen other symptoms that enabled her
to put two and two together. As for the fourth person, it was Cheriton
himself. He was a man of immense practical sagacity. The Lascelles
affair was perfectly familiar to him in all its bearings. He himself was
primarily responsible for it. And none knew better than did he that
youth will be served.
During Jim’s stay at Barne Moor, Cheriton went out of his way to
show him consideration. He behaved like a habitually courteous and
broad-minded man of the world, who, so to speak, knew the whole
alphabet of life, and if necessary could repeat it backwards.
“You have no right to be here, my dear fellow,” he said tacitly to Jim
Lascelles; “but since my Yorkshire friend, Kendal, has blundered, as
one’s Yorkshire friends generally do, and you find yourself in the
wrong galley, behave just as you would under ordinary
circumstances, and, if you have the courage, take up the parable
more or less where you left it. After all, you were brought up together,
and I am only an interloper, and an old one at that.”
It was bold and it was generous of Cheriton to take this course. But
the young fellow Lascelles had behaved so well that he was bound
to respect him. And he had a genuine liking for him too. Therefore he
raised no objection to their spending long hours upon the moors with
only one another for company, while he gossiped and shot birds, and
fribbled and idled away his time indoors among more mature
persons.
Still, it was trying Jim Lascelles somewhat highly. The test was a
severer one than perhaps Cheriton knew. For Jim was confident that
he had only to speak the word for the Goose Girl to marry him by
special license at Barne Moor parish church. Once, indeed, they
found themselves in it, since the Goose Girl was by way of being a
connoisseur in churches; and they had a pleasant and instructive
conversation with the vicar.
However, all’s well that ends well, as Shakespeare informs us. Jim
Lascelles did not obtain a special license, but returned to his mother
like a good son and, shall we say, a man of honor. For it would have
been such a fatally easy and natural thing to marry the Goose Girl at
Barne Moor parish church. If you came to think about it, why should
she be offered for sacrifice? Dickie, of course, would be able to go to
Sandhurst, and Milly would be able to go to the boarding school; but
all the same, it was desperately hard on the Goose Girl.
 CHAPTER XXXIII
EVERYTHING FOR THE BEST IN THE BEST OF
ALL POSSIBLE WORLDS

JIM LASCELLES returned to Balham exactly nine days after he had

left that friendly but uninspired suburb. He had worked hard during
his absence in Yorkshire; the picture of the fair Priscilla had made
excellent progress, and there was a check for five hundred pounds in
prospect on completion. Further, by the interest and undoubted
talent for commerce of his friend Lord Cheriton, Mr. Crosby of the
Foreign Office had been induced to rise to seven hundred and fifty
pounds for the portrait of Mrs. Crosby and her children.
So far as the things of this world were concerned, Jim really returned
to his mother in high feather. The progress he was making in his
profession he felt was out of all proportion to his talent. But it is a
great thing to have a friend at court. So much is done in that way. It
is not always the best picture, or the best oratorio, or the best play,
or the best novel that makes the most guineas in the market-square.
It is one thing to create a masterpiece, and it is another to translate it
into pounds, shillings, and pence. There can be no doubt that Jim
Lascelles had made amazing strides in his art; but all the same, he
was a lucky fellow to have a man like Cheriton to go round with a bell
to call the attention of the picture-buying public to the quality of his
work.
Jim Lascelles would have been less than human had he not been
immensely grateful to Cheriton. And yet he would not have been
human either had he not hated him very sorely. After all, what is the
use of material prosperity if the man who confers it upon you robs
you of the only girl in the world you feel you will ever be able to
marry? Certainly he would now have the means to buy his mother a
new frock or so in order to deprive her of her favorite excuse for not
looking older. But life, even with professional success, was going to
be a hollow business.
However, Jim Lascelles contrived in this crisis to behave with a
discretion that was very creditable to his character. He had gone
down to the depths of late, and, as is often the case with such divers
in deep seas, he had brought up a few pearls. One of these was
resolution. He finished the picture of Priscilla out of hand and drew
his check; and although the season was November, he paid several
visits to Eaton Square and did his best for Mrs. Crosby and her
youthful family. And ever and anon he took his courage in his hands
and spent an hour in further devotion to the masterpiece that was to
make him famous.
It was not until early in January that Jim Lascelles made the
announcement to his patron that the portrait of Miss Perry was
complete. Thereupon quite a number of people interested in art
found their way to the Acacias. They were by no means unanimous
in their opinion regarding its intrinsic merit, but they all agreed that it
was bound to prove one of the sensations of the year.
“An extraordinarily clever fake,” said a critic of the fine arts privately.
“Mr. Lascelles,” said a dealer, “I should like you to give me an option
on all the work you produce during the next five years. I feel sure I
could sell it.”
“We have a new Gainsborough here,” said a third person, who spoke
in an unofficial capacity, “and that is all there is to be said about it.”
About the end of the month Cheriton himself appeared, duly armed
with expert opinion, to see for himself. He was accompanied by Miss
Burden and his fiancée, who was looking thin and unhappy. It was a
beautiful day for the time of year; and in regard to his appearance,
the happy wooer was as fastidious as usual. Never had he seemed
more faultless in his attire or more scrupulously paternal in his
demeanor. He looked long at the masterpiece, and he looked
particularly.
“Lascelles, my good fellow,” said he, “I am forced to arrive at one
conclusion. If you were to paint a thousand pictures, this is
something you will never surpass.”
“Why do you think so?” said Jim.
“Because, my dear fellow, there is growth in it. You began it a callow
stripling; you have finished it, shall I say, a strong man in the
plenitude of his power. I have watched you and the picture grow
together from month to month. It is given to no man to do that sort of
thing twice.”
Jim Lascelles, however, was a robust young fellow—at least, it was
his ideal to be so. He was apt to be on his guard against high-flown
sentiment, yet he knew that Cheriton had spoken the truth.
“You are right,” he said simply. “That canvas has got all I have or all I
ever shall have. I am older now than when I began it, and I hope I’m
wiser.”
“Not wiser really, my dear fellow; we never get wiser. But you have
found yourself. A great career lies before you.”
“You may be right,” said Jim, “or you may not be right, but either way
it doesn’t matter.”
Cheriton inspected the young fellow with the greatest coolness and
impartiality. There was no mistaking that the words were tragic.
Cheriton’s penetration declared them to be so. He took some little
time for reflection, and then he slowly drew a check out of his
pocket-book with an air that was really unfathomable.
“There must be no misunderstanding, Lascelles,” said he, with an air
that was brisk and businesslike. “There is every reason to believe
that the picture of Miss Perry will prove a valuable property. But at
the same time, I hold your promise that I may purchase it on my own
terms. Is not that the case?”
“It is, Lord Cheriton,” said Jim, with indifference.
“I hope the bargain I drove with you may not prove too hard,” said
Cheriton, with an enigmatic smile that Jim Lascelles took not the
least pains to fathom. “But if I may say so, your conduct in allowing
me to drive such a bargain was curiously injudicious. For everybody
tells me that your picture is magnificent.”
“I don’t think it matters,” said Jim, who was looking tired. “Although
one is glad you like it, of course.”
“It must always be pleasant to the artist to have his work admired.
My own comment upon your work is this. I hope, my dear fellow, you
will be able to forgive its extravagance.”
As he spoke he gave the check to Jim Lascelles. The painter,
however, paid no heed to it at first. His instinct was to crush it in his
hands and fling it away, so repugnant was the piece of paper to the
touch. Now that the time had come to part with the sole remaining
solace he possessed, he felt unable to yield it.
This, however, was a weakness he must not indulge. He looked at
the paper perfunctorily, and then he gave a little exclamation. The
check was made out in his favor for ten thousand pounds.
“I don’t understand,” said Jim. “Is there not some mistake?”
“You must constrain your modesty a little, that is all,” said Cheriton.
“People tell me it will be worth every penny of this sum to the next
generation. It is pleasant sometimes to anticipate the verdict of
posterity.”
Jim Lascelles did not know how to act or what to say. In his judgment
this was the most Quixotic proceeding he had ever encountered.
“Really, Lord Cheriton,” he said, “I don’t feel that there are sufficient
grounds upon which I can accept such a sum as this.”
“A bargain is a bargain,” said Cheriton. “I hold your promise that I am
to purchase the picture on my own terms.”
In the flood tide of his bewilderment Jim Lascelles had perforce to
remain silent.
“Don’t forget, my dear Lascelles, that the highest pleasure that is
given to any man is to adopt the role of Mæcenas. And are you
aware that the Red House at Widdiford is in the market, and that six
thousand pounds will purchase it?”
Jim flinched a little. A deep flush overspread his face. This was
sacred ground, upon which it behoved the outside world to tread
warily.
“I hope you don’t mean that the Red House at Widdiford means
nothing to you?”
Jim was not proof against the assault.
“I’m not sure that it does,” he said miserably.
“I wouldn’t be too sure about that if I were you.”
Jim began to look decidedly fierce. In spite of the check for ten
thousand pounds, which he viewed as somewhat in the nature of a
mockery, he showed no disposition to be baited.
“Perhaps it would be wise, Lord Cheriton, not to pursue the subject.”
Cheriton laughed outright at the solemnity of the young fellow’s
manner.
“On the contrary,” said he, “one feels that the subject of the Red
House at Widdiford should be discussed at length. Miss Perry and I
have been over to look at the old place before completing the
purchase.”
“Ah! that is interesting,” said Jim, who was more bewildered than
ever.
“It seems that, in addition to its other lures, the Red House at
Widdiford has peaches in season.”
“Of course it has,” said Jim, who was beginning to feel that Cheriton
was making a rather long excursion in the realms of bad taste.
“Well, my dear fellow, I put it to you—what is the use of having
peaches in season if one has not the appetite to eat them?”
“What, indeed!” said Jim.
“And again, my dear fellow—what, pray, is the use of giving Buszard
a contract for the large size when cream buns lose their savor?”
Jim made no reply, but merely looked miserable.
“Let me tell you in confidence, Lascelles,” said his patron, in a
becomingly low tone, “that even the circus has begun to pall. And as
for Joseph Wright of Derby, the question of his permanent merit is
beginning to appear almost a matter of indifference. Do you feel
competent to give advice in regard to what ought to be done?”
“I am afraid I don’t, Lord Cheriton,” said Jim, rather feebly.
“That is disappointing, for in the past you have shown such a
surprising fertility of ideas and resources. The problem is so serious.
Can one conceive a world in which cream buns have no savor,
circuses no glamor, and in which the Joseph Wrights of Derby are
allowed to ruffle it unquestioned among their betters? Frankly, the
feat is beyond me, Lascelles. And then, too, my dear fellow, the
news that Muffin is to have a new mauve from London to wear in the
spring has excited hardly any enthusiasm.”
“Indeed?” said Jim.
“That is so, I assure you. And to my mind, that is not the least
sinister symptom. I have conferred with the wise woman of Hill
Street, and during my sojourn in the west country also with the
presiding genius of Slocum Magna. And after some discussion of the
pros and cons of the situation, for mon père and ma tante do not
appear to see eye to eye in all things, we are at last in agreement
that something ought to be done to restore the savor to the best
confectionery, and also to insure that no upstart shall occupy without
question the same kind of fauteuil as Rembrandt and Velasquez.
The result of our deliberations is, my dear fellow, that we have come
to the conclusion that you are the man to help us.”
“I!” said Jim, impotently.
“Have you any objection to undertaking such a scheme of
philanthropy?”
“If I could do anything to add to Miss Perry’s happiness,” said Jim, “I
should be just about the proudest chap in the world.”
“Well, it seems, my dear fellow, that you can do so. At least, that is
the opinion that has been arrived at by the experts who have
communed over her case.”
Jim’s heart beat painfully.
“Tell me what I can do,” he said rather hoarsely, “for the best, the
truest-hearted, the most absolutely genuine girl in the world.”
“You can marry her.”
“Marry her?” said Jim, weakly.
“Yes, in the afternoon of April the First, at Saint Sepulchre’s Church.”
“But——” said Jim.
“The oracle of Hill Street thinks the First of June is preferable,
because there will be more people in town, and the presents are
likely to be more numerous. But personally I agree with Mrs.
Lascelles and mon père that April is as good a time as any other for
visiting the Prado.”
“But——” said Jim.
“I forget the inn I stayed at when I was last at Madrid. It was ‘El’
Something, and for some obscure reason it had no aspirate. But one
Ford is the authority for Spain, although, to be sure, a certain Borrow
wrote a famous work upon the subject. By the way, we must not
overlook one important argument in favor of June.”
“What is it?” said Jim, mechanically.
“It is hardly right to expect a new mauve to make its début on the
First of April. Yet there seems no help for it. No ceremony could
possibly be considered complete without it.”
“Am I to understand——?” said Jim, who stopped with ridiculous
abruptness right in the middle of his question.
“By the way, my dear fellow, I have taken the liberty of suggesting to
your accomplished mother that it might help her literary career if she
moved a little nearer to the center. A little flat in Knightsbridge might
be a judicious investment. As you may be aware, publishers as a
race are highly susceptible, and an address in Knightsbridge might
favorably impress them.”
“Do you think so?” said Jim, who did not know in the least what he
was saying.
But there is really no reason to persist in this history. In spite of
scruples, which were as much due to pride as to generosity, Jim
Lascelles married the Goose Girl at Saint Sepulchre’s Church on the
First of April. On that significant occasion the presiding genius of Hill
Street displayed an amount of Christian feeling which, in the opinion
of a contemporary, was without parallel in his experience.
The entire family of Slocum Magna, including Milly, whose pigtail
was the color of a yellow chrysanthemum, and was tied with a
ribbon, came up to London and stayed a whole week at Morley’s
Hotel. Among other things, they all went one day to see the
Exhibition, and found there wasn’t one. Papa dined twice in Hill
Street, and met dukes and people; and he brought back the report
that Aunt Caroline was less worldly than he had feared she was. He
gave his daughter away on the glorious First; and Muffin wore her
new mauve on that occasion. In the opinion of all qualified persons it
was quite as successful as the peerless original. Polly, who took
after her papa, and had more intellect than all the rest of the family
put together, Dickie and Doggo included, looked charmingly proper
in a “costume” more reticent than Muffin’s. Her young man assisted
the Dean of Dunstable, the uncle of the bride, in performing the
ceremony.
Jim Lascelles and the Goose Girl spent a month in the land of
Cervantes and Velasquez. They are living now at the Red House at
Widdiford. Jim is quite likely to be elected to an Associateship of the
Royal Academy before long. At least, he is getting very good prices
for his work, and his “Miss Perry” has been esteemed a rare triumph
for British art. His “Naiad” also, purchased by the Chantrey Bequest,
has been generally and justly admired.
The accomplished mother of the rising artist took the disinterested
advice of a well-wisher, and a fortnight after her son’s brilliant
marriage—the Morning Mirror described it as such—she left “P.P.C.”
cards on the Miss Champneys at the Chestnuts, and moved “nearer
to the center.” It may have been coincidence, or it may have been
cause and effect, but within a fortnight of her installation at No. 5,
Beaufort Mansions, W., “The Fair Immortal” was accepted on a
royalty by an eminent firm of publishers, and made its appearance in
the course of the summer. It won such unanimous approval from the
Press and the public, that it can now be purchased for sixpence of
any self-respecting bookseller in the United Kingdom; its fortunate
authoress has signed contracts for work for the next three years and
has been elected a member of three of the best ladies’ clubs in the
metropolis.
Muffin’s season at Hill Street was an even greater triumph than her
sister’s—but thereby hangs a tale for a wet afternoon. Aunt Caroline,
in spite of her advanced years, is worth “a good many dead ones” at
present, and in the opinion of her oldest friend her manner has more
amenity. Perhaps it is that the influence of youth has been a good
one in her life. It is right to think so since there is no reason to
believe that she has altered her opinion of the clergy.
Polly has not yet married her parson, but she is certain to do so.
Serious people, however, “make haste slowly,” as the wise Italians
say. It is well that they should. Charley has found his way to
Sandhurst all right, and feels himself to be a field-marshal already.
Dickie has lately been presented to a living worth eleven hundred a
year—a really preposterous emolument, considering the widespread
depression in things ecclesiastical. However, in justice to Dickie, it
should be stated that he was always quietly confident that something
would come of his left-arm bowling. And so it ought if you break both
ways.
Milly has been two terms already at her Brighton boarding school. In
the opinion of her mistresses she is the best inside right at hockey
on the South Coast. If she is not chosen to play against Wales in the
forthcoming international match she will be much disappointed.
Entertaining at Cheriton House is still to seek. The thing threatens to
become a national scandal. Comparisons, highly unfavorable to the
present peer, are being constantly drawn by convinced free-fooders
and the praisers of past times. The noble earl, however, is fully
occupied at present in steering a course between the Scylla of Hill
Street on the one hand, and the Charybdis of No. 5, Beaufort
Mansions on the other. The presiding genius of the former locality,
however, defines a coxcomb as a person who never means
anything. Still, it doesn’t do to be too sure in these days.
As an instance of the need for honest doubt, George Betterton did
not lead the fair Priscilla to the altar after all. The world understood
that a religious difference was the rock which sundered them.
Whether George had too little religion and Priscilla had too much, is
one of those things that has never been elucidated clearly. But,
beyond all shade of controversy, they were never brought to the
question. Priscilla made quite a good marriage, all the same. As for
George—well, what really happened to him is a story for one of
those typical English afternoons in which it is really not fit for a dog to
be out. People say that George is much improved lately.
In conclusion, we feel bound to record our opinion that it is gravely to
be doubted whether Jim Lascelles will make as great a painter as
Velasquez. Considering his youth, his attainments, and his temper,
we were among those who predicted a high destiny for the young
fellow, but that was before “the wicket rolled out so plumb.”
Authorities upon the subject are not slow to inform us, however, that
it is better to marry the girl you want to, and to live at the Red House
at Widdiford, and be a county magistrate, and to have a couple of
expensive sons in the Services, and to have your girls dressed by
Redfern and presented at Court, than to appear on a pedestal by
public subscription in front of the National Gallery three centuries
after you have ceased to take an interest in the verdict of posterity.
Quot homines tot sententiæ. These wiseacres may be right, or they
may not be right. It is only the Caroline Crewkernes who are
infallible.
