3. For cutting off bottoms of bottles, make a slight nick with a 

 file, and then mark round with a streak of ink where you want 

 it to come off. Make an iron red-hot and lay it on the nick. 

 This will cause it to expand and crack, then by moving the rod 

 round, the crack will follow. 



To preserve wooden labels. — Thoroughly soak the pieces of 

 wood in a strong solution of copperas (sulphate of iron) ; then 

 lay them, after they are dry, in lime-water. This causes the 

 formation of sulphate of lime, a very insoluble salt, in the wood. 



Liquid putty for glazing. — Take equal parts, by measure, of 

 boiled oil, putty and white lead. Mix the putty and oil, then 

 add the white lead. If the mixture becomes too thick, add 

 turpentine. Apply with a putty-bulb. 



To prepare paper and cloth for hotbed sash. — 1, Use a sash with- 

 out bars, and stretch wires or strings across it to secure as a 

 rest for the paper. Procure stout but thin manila wrapping- 

 paper, and paste it firmly on the sash with fresh flour paste. 

 Dry in a warm place and then wipe the paper with a damp 

 sponge to cause it to stretch evenly. Dry agafn and then apply 

 boiled linseed-oil to both sides of the paper, and dry again in a 

 warm place. 



2. Saturate cloth or tough thin manila paper with pure raw 

 linseed-oil. 



3. Dissolve \% lbs. white soap in 1 qt. water ; in another quart 

 dissolve \% oz. gum arable and 5 ozs. glue. Mix the two liquids, 

 warm and soak the paper, hanging it up to dry. Used mostly 

 for paper. 



4. 3 pts. pale linseed-oil ; 1 oz. sugar of lead ; 4 ozs. white rosin. 

 Grind and mix the sugar of lead in a little oil, then add the other 

 materials and heat in an iron kettle. Apply hot with a brush. 

 Used for muslin. 



Waterproof paper. — Waterproof paper, transparent and imper- 

 vious to grease, is obtained by soaking good paper in an aqueous 

 solution of shellac and borax. It resembles parchment paper in 

 some respects. If the aqueous solution be colored with aniline 

 colors, very handsome paper, of use for artificial flowers, is pre- 

 pared.
