 as soon as it is possible to get ck r make him 



i out his tank, and don't let him haul it around till 

 the boiler gets it all. 



Allow me just here to tell you how to construct a 

 good tank for a traction engine. You can make the 

 dimensions to suit yourself, but across the front end 

 and about two feet back fit a partition or second head ; 

 in the center of this head and about an inch from the 

 bottom, bore a two-inch hole. Place a screen over this 

 hole on the side next the rear, and on the other or front 

 side, put a valve. You can construct the valve in this 

 way: Take a piece of thick leather, about four inches 

 long, and two and a half inches wide; fit a block of 

 wood (a large bung answers the purpose nicely) on 

 one end, trimming the leather around one side of the 

 wood, then nail the long part of the valve just above 

 the hole, so that the valve will fit nicely over the hole 

 in the partition. When properly constructed, this valve 

 will allow the water to flow into the front end of the 

 tank, but will prevent its running back. So, when you 

 are on the road with part of a tank of water, and start 

 down hill, this front part fills full of water, and when 

 you start up hill, it can not get back, and your pumps 

 will work as well as if you had a full tank of water. 

 Without this arrangement you cannot get your pumps to
