The chamber-acid should be diluted with its bulk of water be- 

 fore being applied to bones or other phosphate of lime. 



Within a few months two large deposits of native bone-earth 

 have been discovered in this country — the one at Dover, New- 

 Jersey, by Dr. Jackson and Francis Alger, Esq., of Bostou ; and 

 the other at Crown Point, Lake Champlain, by Prof. Emmons. 



That, in the New- Jersey locality is very pure and compact, it be- 

 ing twice the weight of bone-dust and containing an equally large 

 per centage of phosphate of lime. When pulverized it dissolves 

 readily in sulphuric acid, forming the super-phosphate, and will 

 prove of inestimable value to our farmers. A company has 

 been chartered by the Legislature of New- Jersey for working 

 this mine, and many hundred tons have been shipped to Eng- 

 land, and there bought readily by the farmers at from X5 to jGT 

 per ton, ($25 to |35,) while our own farmers, with but few ex- 

 ceptions, are inactive in its use. 



Many thousands of acres in the States of New-York, Massa- 

 chusetts, Ohio, and elsewhere which produced large crops a few 

 years since, now refuse to do so, and in many ca.'^es simply from 

 absence of phosphoric acid in the soil, the whole having been 

 parted with as constituents of former crops, and composing the 

 bones of animals raised upon these farms. Experiment has 

 proved that turnips and other crops raised on soils fairly charged 

 with phosphate of lime, are more nutritious and have better 

 keeping qualities than those raiseil by the use of farm-yard mar 

 nure alone; indeed, the nitrogenous manures are always 

 more effective after the application of super-phosphate of lime. 

 I have many acres of ruta-bagas this year raised as a second crop, 

 after early vegetables, by the use of super-phosphate of lime, 

 and yielding more than one thousand bushels per acre. All the 

 root crops are doubled in quantity by its use, while all other 

 crops are materially improved. By reference to the analysis of 

 vegetables, but few will be found the ashes of which do not 

 contain phosphate of lime, and maximum crops cannot be raided 

 from soils deficient in this amendment. To the dairyman, this
