The acknowledged points of Moore & Richardson's machines are good 

 boilers and strong work. Elegance and perfection of detail are not made 

 a cardinal point as with some Eastern builders, and yet there is nothing 

 ugly or ungainly about the machines. 



For a 15 X 22 inch cylinder, the firebox is 52 x 41 inches. The barrel 

 is 42 inches diam. at the front end, and 43 at the back end. There are 

 122 two inch flues, 10 feet long and % inch apart. The good distance 

 between the flues is an important item, not half well enough undersood 

 by builders generally. 



The frame consists of a bar 4x2)^ inches, running straight from breast 

 to back beam with pedestals forged on. Another bar, or strap, from just 

 behind the cylinders, extends to the foot of the front pedestal and another 

 connects the pedestals, besides the jaw braces, which are secured by lugs 

 and bolts. The lower strap is joined to the upper one behind the cylinder, 

 by a key let into both, and by 3 bolts. A heavy angle iron connecting 

 the frames in front, holds the wooden breast beam. The center and out- 

 side bearing truck, a very strong though somewhat complicated device, 

 will be described at another time. 



The equalizing beam is under the main frame, and the springs above, 

 as usual. The Rogers expansion brace is employed on the fire-box. The 

 center line of truck is 4 inches in front of the forward end of the smoke 

 arch, thus throwing more weight than usual on the drivers. The foot 

 board is of boiler plate, and the back braces running to it from the fire- 

 box, are unusually heavy. No provision is made for expansion, as is 

 sometimes the case, hence the boiler rises as it expands. It is questionable 

 whether there is any virtue in a back brace which has an expansion ap- 

 paratus. The slide rod yoke is of cast iron, with a leg to rest on each bar 

 of the frame, to which it is securely bolted. 



The cylinders are not level, being over the back truck wheels, instead of 

 between the wheels. The cross head is hollow, and the rods flat, and much 

 smaller at the ends (inside the heads) than in the middle. Some builders 

 make them straight. Here is another open question. They are forged in 

 a solid bar, no welding or scrap work being allowed. 



The cylinder fastening is light and strong. The smoke arch being 

 round, a flange from about the center of the cylinder projects straight to- 

 wards it, and another from the valve seat, is parallel with the first, just 

 above it. The two flanges are joined by the steam and exhaust pipes, 

 which are cast between them, and by a heavy flange or plate, embracing 

 a portion of the smoke arch. The frame is immediately under the lower 

 flange, and holds it fast by lugs and wedges, as well as bolts. 



The valve gear is the suspended link. The eccentric rods are 46 inches 

 long, and the radius of the link 42 inches, which of course is the length
