Lettuce ( Variety Hanson) . 



Seventy Plants. 



Spinach ( Variety Neio Zealand) . 



From our observations as above reported, extending over 

 three years, we may draw the following conclusions : — 



Potash in the form of sulphate has given the most satisfac- 

 tory results, as compared with muriate, in the case of pota- 

 toes, tomatoes, lettuce and spinach, and with onions during 

 the present season. 



Nitrogen in the form of nitrate of soda has given us, with- 

 out regard to the potash source, the most satisfactory returns 

 in case of spinach, lettuce, potatoes and tomatoes, and witL 

 onions during the present season.
