AMERICAN INSTITUTE. 317 



The Secretary read a letter from the Consul General of Austria, 

 who has established a house there for the sale of American agri- 

 cultural implements and machinery. This house has branches 

 in all the principal cities of Austria. It would appear that the 

 American ash answers better than any Austrian wood. The 

 prices there are much in advance of the prices here. 

 LIQUID MANURE. 



A letter was read from Dudley S. Gregory, Esq., of Jersey City, 

 which is of importance sufficient to warrant its being copied in 

 extenso : 



Dear Sir: My thoughts have been directed to the preservation 

 of liquid manure now, when I am enlarging my stable, and it 

 seems to me this subject is very much neglected in this country. 

 Allow me to refer you to an interesting account and extraordinary 

 yield in consequence of the use of this manure. You have pro- 

 bably in your library, and if not, ought to have — [it is there] — 

 the work of Henry Colman, called European .>6grictilture and 

 Rural Econcnnj, at page 162, vol. 2, you will find the account 

 I refer to, and also an extract of the value of human urine, of 

 which Liebig says 100 joarts are equal to 1,300 parts of the fresh 

 dung of a horse, and 600 of that of the cow. 



If this be so, what an opportunity for your corporation to 

 develope through the action of your institution the preservation 

 and use of the immense quantity of this liquid every day running 

 to waste on the public temple in the rear of the City Hall, as well 

 as in the city generally. 



It seems to me that a premium might be well bestowed in 

 inducing the stables for omnibus horses, car and baggage livery 

 stables, to preserve and encourage the use of liquid manure, so 

 much more valuable than the substance of stables. 



Yours, D. S. GREGORY. 



ERRORS IN FARMING. 



Solon Robinson read a letter from a farmer in Cumberland 

 county. Pa. The writer says : 



" It is written with the hope that it may attract the attention 

 of some person — perhaps some members of the American Insti- 

 tute Farmers' Club — to the greatest evil that exists in our whole 

 system of farming, and is a subject worthy the attention of every 

 one who values the agricultural prosperity of our country. 



" I have watched with much interest the call on the farmers, 

 and the response which has come from many sections of the
