No. 129.] 299 



meeting was held here. We m.iy be able to employ one teacher 

 fir^^t, and then anolher, until tlieie are enough to leach all — it 

 wouhl soon make farmers at work without teaclurs. Take such 

 men as Bement, Ambrose Stevens i\>v cattle, &:c., A. Brill llr 

 root crops, Norton lor agricultural science generally. 



Lectures should be delivered in every toAvn and district by 

 conjpetent persons uho were scientific and of course practical. 



Mr. Gc'Tge Dickey — Would it not be •well to get up suitable 

 petiii'ins now-, addressed to the present Legislature in relatiun to 

 this lm]x>rtant question? 



Professor Mapes — T have delivered about one hundred and 

 fifty agricultural lectures, and soaie of my hearers have become 

 rabid. A sort of furor on tlie subject of agricultural improve, 

 ment has seized them. Dr. J. Marshall Paul went to look at a 

 tract of fuur thousand acres of poor land on sale at about fue 

 dollars an acre. He bought four hundred acres at that price. 

 He has underdrained two hundred of them and they are now 

 worth une hundred and fifty dollars an acre. 



Mr. Meigs — As to drain?, I notice an advertisement in the 

 London Times of 27th of May last, of an exhibition of a machine 

 laying drain pipes at once without trouble. Place of exhibition 

 three milts from the Crystal Palace. 



Professor Mapes — There is a plan now in operation (as I under- 

 stand,) by which it can be done at one operation, five feet deep, 

 and Willi economy. As to drain tiles we can now have them 

 from a manufactory on Stateu Island, by application to George 

 H. Bnrr, at No. 25 Cliff street. The tiles of two inches bore are 

 Sold fur nine dollars a thousand, those of larger calibre for more. 



Dr. Antisell — I find that the phoFphorile or apatite contains 

 ninety-two i»er cent, of ph( S})hate of lime. I have since that 

 seen I he Apatite from Crown Point described by Professor Em- 

 mons. It is siirrouiuled by serpentine which, ground with it 

 colors ir, and it is of less valne. The pure Apaiite is white. 

 The niHSs in Jer-ey is equal to the example which has been ex- 

 hibited here ; it is contaiutd, in mine, in a gangue of feldspar.
