sformula, the maximum tractive power is•over 9,000 pounds. On a trial trip up a grade varying from50 to 58 feet to the mile, three miles inlength, the car maintained a speed ofthirty miles per hour, hauling a regularpassenger coach as a trailer; while on alevel, the car alone, with a quarter-milestart from the first mile post, covered fivesuccessive miles in 5 minutes 55 seconds,as follows: 1st mile, 1 minute and 20 seconds. 2d mile, 1 minute and 10 seconds. 3d mile, 1 minute and 5 seconds. 4th mile, 1 minute and 7 seconds. 5th mile, 1 minute and 13 seconds. As will be seen by the engravings, theboiler is surrounded by a circular casting•on which is a groove in which rest about125 ij^-inch hardened steel balls. A cor-responding casting is attached to theframing of the car, resting upon theseballs, which allows the locomotive toswivel freely in passing curves, the sameas an ordinary truck. The steam andexhaust pipe connections pass from theboiler to the cylinder inside of this ball

Compressed air is usedfor whistling, for ringing the bell and forshaking the grates. The motion is ar-ranged with a view to each part beingeasily reached, and the Walschaert valvemotion employed makes that part verycompact. The fuel used in car is coke or anthra-cite coal, and the car has sufficient fueland water capacity to enable it to runsixty miles without replenishing it. ft ft ft An Efficient Tie-Plug Machine. The tie plug cuts no small figure in themaintenance of permanent way, in plug-ging up old spike holes in ties, but forwhich care a tie would soon be fit for thepyre at the track side, all on account ofthe decay invited and fostered by water that amount of material, making themconvenient to store and handle, and alsoeasy to pull apart by the section men.
