MMING SOILS AND PLANTS.

have usually been obtained upon the limed plat manured with 

 sulphate of ammonia instead upon the other limed plat. 



The results with cabbages grown with the aid of nitrate of 

 soda are at the left, and they 'show its superiority to sulphate 

 of ammonia. Liming proved helpful in both cases as shown 

 by the larger piles. 



The watermelon seems to be quite at home upon acid soil. 

 The product with nitrate of soda is at the left, and with sul- 

 phate of ammonia at the right. The smaller yields in both 

 cases were upon the limed plats. It is remarkable that the 

 watermelon should be injured by liming, and that it should 

 thrive splendidly upon the unlimed plat receiving sulphate of 

 ammonia, where upland cress, Kafifir corn, sorghum, barley, 

 the cantaloupe, and many other varieties of plants utterly fail. 



Tlie cantaloupe is the opposite of the watermelon ! The 

 crop from the plats receiving sulphate of ammonia were al- 

 ways inferior to the corresponding ones manured with nitrate 

 of soda. In each case the limed plats produced the larger 

 product. In fact it was seldom, if ever, that fully ripened-
