like the other rock- work described, but in shades it should 

 be dressed with glue and grated cork, and colored with 

 paste and dry colors. The coke can be fastened by filing 

 a flat surface and gluing it m jDosition. 



BRONZED ROCK-WORK. 



Nearly all varieties of artificial rocks can be bronzed, 

 though the following is the best method to pursue. Form 

 the rocks of cork and coat them with plaster, care being 

 taken to fill all crevices. When dry, cover witii a sizing 

 of thin glue, and color, and when the latter is also dry, 

 cover with thin, white varnish, working in bronze powder 

 with a brush. Bronzes in powder of all colors can be pro- 

 cured at paint stores. 



PAPIER-MACHE ROCK-WORK. 



This material may be modelled over a body of any kind 

 that is first coated with glue. While it can be finished 

 with any dressing, it takes bronze the best. 



FANCY ROCK-WORK. 



Bright-colored rocks can be made in various wa3^s ; the 

 following is the most successful : Construct a body of 

 cork, as directed, or of thick pine bark. Cover with thin 

 hot glue, and dust quickly with grated cork, prepared 

 with a common tin grater. When dry, put on dry colors 

 with a brush and paste. A dark ground should first be 

 made with umber or lamp-black, then lighter colors add- 

 ed, and the whole very faintly tinged with orange chrome, 

 rose, and vermiHon. Fancy rook-work should only be 

 used with birds of bright plumage.
