Melt the solder in a ladle and pourit on the joint. When the pipe becomesheated by the molten solder, the solderwill begin to adhere, and as it accumu-lates on the joint it should be wipedinto shape with a piece of strong clothgreased with tallow. SLIP OF DRIVERS. (56) E. M. P., Carnarvon, la., writes:I had an argument with a fireman friendof mine regarding a locomotive passingaround a curve. I claim that the drivers,on a certain side must slip on the rail asmall amount, for if the two rails werelaid out straight, the outside one would. TAV EUrOGE AT DUNDEE, SCOTLAND. be the longer and so the wheels on oneside would slip slower than the speedof the engine would be on the straighttrack, or the wheels on the other sidewould slip on the rail faster than thespeed of the engine, assuming that thedrivers on the opposite side of the slip-ping ones grasped the rail firmly. Kindlygive me your opinion. A.—You are rightenough about the slip of the drivers. Asthe wheels on both sides of the engineare the same size and are rigidly securedto the axle, both pass over the same dis-tance each revolution on straight a curve the length of the inner railis necessarily shorter than that of theouter rail. If the rails of a curve werestraightened out and it was found, sayfor example, that the outer one was 20ft. than the inner one, the slip ofthe drivers would be just that the wheel on the longer rail did nots
