any further manuring, and will probably get the largest crop 

 that soil and season will allow, or, at any rate, a crop not very far 

 short of that. Unless, however, he has been guilty of such 

 extravagance, it would be better to plant winter lettuces after a 

 crop that has been moderately dunged, and to use a dressing of 

 about 4 cwt. of superphosphate and 2 cwt. of nitrate of soda per 

 acre. 



S winner Lettuces. 



Summer lettuces, however, should not be left without dung, 

 as they have to live through possible drought in a critical time 

 of the year ; though, if the season should happen to be favour- 

 able, they will thrive well enough without it, provided they be 

 abundantly fed with other manures. On the whole, a light 

 dressing of dung, from 4 cwt. to 6 cwt. of superphosphate, and 

 2 cwt. of nitrate of soda per acre, will form a good dressing, and 

 our results appear to indicate that, on most soils, no special 

 application of potash salts need be made for this crop.

It will be seen that the combination of chemical fertilisers and 

 light dung has given much better results than heavy dunging. 



The effect of potash salts on this crop is very remarkable.
