In making this mould there were no core prints, or bear-ings at the ends, for the core to rest on. The mould endedon the outside of tlie flanges, and to form the face of theflanges and core prints there were half-pricked plates used,as shown at F on the plan and end elevation. The trunnionscast on these plates made them easy to handle. When the bottom part of mould was set down to be got readyto cast, one of these half-plates Avas set up against each endof the flanges or mould, and wedged up until the half-round TWO WAYS OF MOtTLDiNG CHOOKED l>IiPES IN LOAM. 139.

After this, the second craneis hitched to the upper handles, 1 and 2, and the copehoisted up clear from the ground. Then by hoisting uponthe crane, as shown, the cope is completely turned over,after which one crane can handle it, and place it whereverwanted. After the cope is placed truly on top of the bottom part ofthe mould, in doing which there can be no trouble, as thetop ends are all open so that the moulder can put in hishands and feel the two joints as well as see them, two upperend plates, which are not shown, are lowered over the endsof the core and pressed up against the face of the
