No. 23. justable tail bearings. The use of tail rods is quite novel inthis country, although very common in Europe, and they wereintroduced to remove the strain which otherwise falls on thebottom of the cylinder. While the reduction in pressure onthe bottom of the cylinder from the piston does not amount tovery much during light loads, it is considerable during heavyloads, on account of the fact that the steam enters on top ofthe piston.
