through a mill so constructed as to ofraniilate the coal with the 

 least destruction of its capillaiy structure, thus increasing its power 

 for the fixation of gases. 



The portions of hard wood ashes and salt are mixed with the 

 charcoal while being granulated ; the three are then immediately 

 mixed with the gypsum and lime, and packed in substantial bar- 

 rels rendered air-tight by the application of a coating of plaster of 

 paris stucco^ on their inner surface. 



With this cheap disinfecting material, which in itself is a good 

 manure, Dr. Thompson thinks the w^hole garbage product of the 

 city could be converted into one of tho richest fertilizing materials; 

 thus preventing a great waste, while the health of the city would 

 be improved. The same material may be used for deodorizing 

 privy vaults. Its value as a disinfectant has been highly recom- 

 mended by some of the first chemical authorities in the country. 



Dr. Edward E. Squibb, in a paper on Disinfectants, published 

 in Med. Rec, Ma}^ 15, says : "Freshly prepared lime and char- 

 coal, in the proportion of about tw^o parts lime and one charcoal, 

 ground together into coarse powder, and the powder at once 

 securely packed in barrels, would fulfill all the indications to the 

 use of both agents, and would constitute as good a general agent 

 for all the various uses in the form of a dry powder, as could be 

 produced in the present state of knowledge, and if the community 

 would accept the accumulated evidence of character and settle 

 down upon the use of this, the greatest general good would be 

 likely to result. Such compound might be appropriately called 

 ' Calx Powder.' " 



Privies deodorized with this material would only require to be 

 cleaned in winter time, and then by a further addition of the 

 deodorizer, the material could be barreled for the farmer's use. 

 Dr. Thompson stated that the Lodi Manufacturing Company sells 

 80,000 bbls. per annum of poudrette, which is composed of a 

 small quantity of the solid part of the privy contents and a large 

 part of muck from the Newark salt meadows. 



Cheap Paint for Farm Buildings and Fences. 

 Prof. S.D. Tillman. — Some questions having been asked the clul) 

 about the best out-door paint, I would recommend as the cheapest 

 and neatest covering for fence \and rough work a mixture of lime 

 paste and skimmed milk. The best preparation would be made 

 by mixing lime with curd, and using milk or whey for diluting the
