76 The Horticulturist' s Rule- Book. 



Paint and Protective Compounds, continued. 



piece of camphor as large as a hen's egg. Melt over a slow 

 fire. Have both grease and leather warm and apply with a 

 brush. 



3. 1 pt. of linseed oil, mutton suet, 6 ozs. of clean 



beeswax and 4 ozs. of resin ; melt and mix well. Use while 

 warm with a brush on new boots or shoes. 



For Cloth for Pits and Frames.— Old pale linseed oil, 



3 pts. ; sugar of lead (acetate of lead), 1 oz. ; white resin, 



4 ozs. Grind the acetate with a little of the oil, then add the 

 rest and the resin. Use an iron kettle over a gentle fire. 

 Apply with a brush, hot. 



For Paper. — Dissolve \%Vos. of white soap in 1 qt. of 

 water; in another qt. of water dissolve lj^ozs. of gum 

 arabic and 5 ozs. of glue. Mix the two liquids, warm them 

 and soak the paper in it and pass through rollers, or simply 

 hang it up to dry. 



To Prevent Metals from Rusting.— Melt together 3 

 parts of lard and 1 part of powdered resin. A very thin 

 coating applied with a brush will keep stoves and grates 

 from rusting during summer, even in damp situations. A 

 little black lead can be mixedowith the lard. Does well on 

 nearly all metals. 



To Prevent Rusting of Nails, Hinges, Etc.— 1 pt. of 

 linseed oil, 2 ozs. black lead ; mix together. Heat nails red- 

 hot and dip them in. 



Amount of Paint Required for a Given Surface.— It is 

 impossible to give a rule that will apply in all cases, as the 

 amount varies with the kind and thickness of the paint, the 

 kind of wood or other material to which it is applied, the age 

 of the surface, etc. The following is an approximate rule : 

 Divide the number of square feet of surface by 200. The re- 

 sult will be the number of gallons of liquid paint required 

 to give two coats ; or divide by 18 and the result will be the 

 number of pounds of pure ground white-lead required to 

 give three coats. 

 4. Glues. — 



Liquid Glue. — 1. Dissolve 2 lbs. of best pale glue in 1 qt. 

 of water in a covered vessel, placed in a hot water bath ; 

 when cold, add to it 7 ozs. of commercial nitric acid. When 

 cold put in bottles.
