Value of net average increment: unlimed, $0.52; limed, $65. 

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



The yield upon the limed portion of many of the j^lots 

 this year is, as was anticipated, much l)ettcr than last year, 

 although the tops on all parts of the field were somewhat 

 prematurely killed hy l^light. 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 nearly 500 bushels to the acre of well-cured onions 

 upon the limed half of the plot y which has been yearly manured 

 with nitrate of soda^ dissolved bone-blach and muriate of pot- 

 ash; while on the unlimed portion of the sa^ne plot ive have a 

 yield of 13G.9 bushels to the acre. The lime has evidently 

 proved highly beneficial. 



Particular attention is called to the fact that we nowhere 

 obtained a fairly good crop except iipon those jjlots to which 

 2)otash has been yearly supplied. The limed p)ortion of the 

 plot, which has yearly been manured with muriate of potash 

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

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

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

 yield at the rate of 380 busjiels. These figures make it j^er- 

 fectly evident that potash is an exceedingly important manure
