Value of net average increment : unlimed, $0.52; limed, $05.00. 

 Financial result: unlimed, $5.88 loss; limed, $59.26 gain. 



The yield upon the limed portion of many of the plots 

 this year is, as was anticipated, much better than last year, 

 although the tops on all parts of the field were somewhat 

 prematurely killed l)y blight. The heavy application of lime 

 made in that year appears to have corrected in large meas- 

 ure the faulty soil conditions. We have this year a crop at 

 the rate of near} y 500 bushels to the acre of well-cured onions 

 upon the limed half of tlie plot, which has been yearly tnanured 

 with nitrate of soda, dissolved bone-black and muriate of p)ot- 

 ash; while on the unlimed portion of the same plot ice have a 

 yield of 136.9 bushels to the acre. The lime has evidently 

 pi'oved highly beneficicd. 



Particular attention is called to the fact that we noinhere 

 obtained a fairly good crop exceptt upon those plots to which 

 potash has been yearly supplied. The limed piortion of the 

 plot, which has yearly been manured lOith muriate of potash 

 alone, gives a yield at the rate of 383 bushels to the acre; 

 the nitrate of soda and the jiotasJi give a yield at the rate of 

 about 311 bushels; the dissolved bone-black and potash, a 

 yield at the rate of 380 bushels. These figures make it per- 

 fectly evident that potash is an exceedingly important manure
