potters use is the right sort ; or that known as " blue clay" will answer a 

 good purj)ose in its natural condition. Even such as brick-makers use cati 

 be washed of all its iniijurities, bv tlioroni^hlv niixin;' it witli a lar-'o bulk 

 of water, and letting it settle and then draw oti' the water, and also reject 

 the bottom of the mass, which will contain all the sand. 



To prepare clay for paint, first dry it, either in the sun or liy lire, and 

 then pulverize ft line, whieh may be done witli a cannon-ball in a swin-diif 

 iron pot. Then sift it, and mix with boiled linseed oil, pretty thick, and you 

 will have just as good a fire-proof paint, or a weather-protecting paint, as 

 any tliat arc sold as such in the shops. 



In some localities soft slate, or slate-dust from a manufactory, can be had, 

 and that will make a good " mineral paint." 



302. Zinc and Lime Whitewash Taint.— Take a clean barrel that will liold 

 water. Put into it half a barrel of quicklime, and slake it by ponring over 

 it boiling water sutheient to cover it four or five inchi's deep, and stirrin;; it 

 until slaked. When quite slaked, dissolve it in water, and aild two iwuiids 

 of sulphate of zinc and one of common salt, wiiich in a few days will cause 

 the whitewash to harden on the wood-work. Add sufficient water to bring 

 it to the consistency of tliiek whitewasli. 



To make the above wasli of a pleasant cream color, add three pounds of 

 yellow ocher. 



For fawn color, add four pounds of umber, one pound of Indian red, anc 

 me pound of lampbhick. • 



For gray or stone color, add four pounds of raw umber and two ponnds 

 of lampblack. 



The color may be put on witli a common whitewash brush, and will be 

 found much more durable than common wiiitewash. 



3G3. Stucco Whitrwash. — To make a brilliant stucco whitewash for all 

 buildings, inside and out, take a bnslu'l of ch'an lumps of well-burnt lime, 

 shdced ; add one iburth pound ol' whiting or burnt alum pulverized, one 

 l)Ound of loaf sugar, three quarts of r^'c flour, made into a thin and well- 

 boiled paste, and one pound of the cleanest glue, dissolved. This may bo 

 put on cold within doors, but shouhl be applied hot outside. ^ 



The following is another receipt for stucco whitewash : Take half a bushel 

 of nice unslaked lime, slake it with boiling watiT, covering it during the 

 ])rocess, to keep in the steam. Strain tlic liquid through a fine bievo or 

 strainer, and add to it a peck of salt, previously well dissolved in water; 

 thi'ee pounds ground rice, boiled to a thin pa.ste, and stirred in builing liof ; 

 half a pounil Si)anish whiting, anil a jn.und of clean glue, whicli has bot-n 

 jireviously dissolved by soaking it first, and then hanging over ii slow fire, 

 in a small kettle inside a large one filled with water. Add five gallons of 

 hot water to the mixture, stir it will, and let it stand a few days covenMl 

 Irom the dirt. It should bo put on quite hot; for this jturposo it can bo 

 kejit in a kettle on a furnace. It is said that about a pint of this inixturo 

 will cover a yard square of the outside of a house, if properly npplietl.
