Are two peunds of soda too much to apply to 100 square feet of ground for lettuce.

In such experiments one plot should always be left with no fertilizer, to 

 serve as a standard by which might be compared the relative values of the 

 diflFerent fertilizers or mixtures used. From the fact that the plants were killed 

 when the nitrate of soda was used, shows that it was applied in too large a 

 quantity. From ^^ to ^^ lb. would be nearer the proper quantity to use on 1,00 

 sq. ft. of ground. It might be applied to the best advantage by dissolving it in 

 a pail of water and then applying it with a sprinkler. Care should be taken, 

 however, that the other plots in the experiment receive an equal quantity of 

 water. Nitrate of soda can be most economically used by applying it in small 

 quantities at intervals of ten days or two weeks. 



Hardiness of Japan Plums. 



8J2 SiK, — Are the .Japan plums. Abundance, Burliank, Satsuma and WiUftrd, aa 

 hardy as the Lombard or the Bradshaw. 



J. D. Stewart, Aitlctn's Ferry, P. E. I. 



The Japan plums are not as hardy as the Lx)mbard, although they appear 

 to be doing well in southern Ontario. Will our subscribers who have had 

 experience with them farther north, please say whether they are hardy with 

 them. 



Quinces. 



843. Sir, — Are the Champion and Rea's Mammoth quinces as hardy as the Lombard 

 plum ? Compare season of ripening with Lombard plum. J. D. Stewart. 



So far as our experience goes in southern Ontario the quinces are as hardy 

 as the Lombard plum, but we have not yet received results of any experiments 

 with them in our stations farther north. The season of ripening of the quinces 

 is at least two or three weeks later than that of the Lombard plum. 



Plum Baskets. 



844. Sir, -What quantity of plums does the plum basket of Ontario contain ? 



J. D. Stewart. 



The plum and peach basket of Ontario are the same size and hold about a 

 peck and a half.
