Two large boilers, 16 feet long and 6feet in diameter, furnish steam for thelarge cylinders, the air compressor for the i8s \ariou3 operations of filling the cylinderswith ties, steaming them, forcing the solu-tion into the wood, come along in a regu-lar succession in each of the three cylin-ders, so that only one of them is open at atime.

A very large surface condensercomes between the cylinders and the airpump. The water which flows through the tubes<ii the surface condenser, and around theair cylinder of the compressor, flows intoa large underground cistern of exhaust steam from both air pumpspasses through a coil of 4-inch pipe in thiscistern and is also condensed, so there isa supply of hot water for the boilers, partof It condensed water. The cylinders arecharged with steam alternately, so as tohave a steady draft from the boilers. The Putting Pipes Out of Sight. The new class H-6 (consolidations)of the Pennsylvania Railroad are withouta single pipe outside the jacket in front ofthe cab. Mr. Vogt has recently put theLeach
