11. Make the countersunk holes in the edge of the secqnd 

 piece as before ; fill in with plaster all the remaining space 



between pieces 1 

 and 2, and we 

 have the third 

 piece, which com- 

 pletes the mould. 

 As soon as this 

 hardens, tap the 

 mould lightly all 

 over with a small 

 mallet, to loosen 

 it from the object,

ly separated and the apple taken out. Take one part of gum 

 sandarac (dissolved in ninety -five per cent, alcohol) and three 

 parts of white shellac, also dissolved, and mix them. They will 

 form a solution a little thicker than water. Have the mould 

 perfectly dry, and apply this solution to the entire inner sur- 

 face of it with 

 a small paint- 

 brush. The so- 

 lution will be 

 absorbed at first, 

 and you must 

 continue to ap- 

 ply it until the 

 inner surface 

 has an egg-shell 



gloss, which is 

 sufficient. Then 

 oil the inside 

 with lard oil. 



12. P^^t together pieces 1 and 2 of the mould, cut a groove 

 around them to hold a stout string, and tie it tightly to liold 

 them together. Then mix some plaster, and fill each piece (1 

 and 2) about half full, walling it up the sides with the finger, a
