nothing can excel it. Without smoke, ashes, dust, or anything of 

 the kind, it is the ne plus ultra of cleanliness, and may be used in 

 a parlor without fear of soiling the finest carpet. 



Another recommendation of this apparatus is its movability. It 

 can be carried as easily as a table, and the heat applied in a parlor, 

 in an out-house, out of doors, anywhere. On the whole, the referee 

 cannot but regard this invention as the most important of any that has 

 been given to households since the late Elias Howe earned the per- 

 petual gratitude of womankind by giving them the sewing machine. 



J. B. LYMAN. 



Prof. S. D. Tilman said the invention of Mr. Young was not 

 entirely novel. He had succeeded better than any other person in 

 getting complete combustion. Yet he thought some ill conse- 

 quence might come of using the stove in a tight room. It must 

 throw some products of combustion into the room, as carbonic 

 acid, and maybe a little carbonic oxide in some cases. At any 

 rate, it would be safe to make arrangements for full ventilation of 

 such rooms. He thought the arrangement a safe one. 



The report was accepted. 



DR. grant's trench PLOWS. 



Several of the plows were exhibited by Mr. Bro^vn, of the 

 Peekskill manufactory. 



Mr. Horace Greeley. — Having heard that Dr. Grant had invented 

 a new plow, I went up to see it work. He has several kinds — some 

 for common work, and others for deep plowing, and in rough 

 ground. I consider deep plowing a remedy for the woes of this 

 country. The large plows are drawn by two yoke of oxen, which 

 I think are not enough. The soil, where the trial took place, is 

 some ten inches deep of mold, and the rest gravel stones, up to the 

 size of a lap-stone. Twice going through, so thoroughly mixed 

 the earth, that one could not tell whether the mold was more in 

 one place than in another. I never saw any trenching done better. 

 No garden or orchard ought to be planted unless trenched two feet 

 deep, so that the roots can penetrate to the moisture. Two feet is 

 not deep enough, but I am so modest I stop here. I believe if our 

 orchards were planted on such grounds they would never fail. 

 The Belgians, who are the best farmers in the world, have come to 

 the conclusion that ground should be stirred at least three feet 

 deep. With such a plow as this, four yoke of oxen, two men and 

 a boy, half an acre can be trenched per day j and being properly
