Length, fourteen inches; Width, two and three-quarter inches; Thickness, about one-eighth of an inch; this is called the Foundation.

Having cut the exact size, next proceed to make on it, in pencil, the plan as detailed in [Fig. 1], as follows: Rule the two parallel lines A E, B F, at distances of a quarter of an inch and three-eighths of an inch respectively from one edge; rule C G, D H at the same distances respectively from the other edge. Next measure off from one end (which you had better mark ‘Front’) half an inch, then one inch and a quarter, one inch, one inch and three-quarters, etc., as on plan (this must be done on both edges); rule lines across where the words ‘RAISE UP,’ 1, 2, 3, 4, are marked. The shaded parts between the parallel lines should be shaded on your plan as in the diagram. These shaded parts are now to be cut out with a sharp knife. It requires both patience and care to prevent the wood splitting, but a little practice will enable you to do this easily and skilfully. These cut-out spaces (as will be seen afterwards) are for the wheels.

The foundation is now prepared, and the next process is to cut out four boiler ends, or ‘Raise-ups,’ as they are termed, 1 and 2 for the front, 3 and 4 for the back of boiler. They are all different, and are formed as follows: On four pieces of thick card (No. 2a in [list] of materials) describe circles with radius one and one-eighth of an inch (equal to half the distance from A D); in Nos. 2 and 3 describe a second circle, with radius not quite a quarter of an inch less.
