490 ReEpoRT OF THE HORTICULTURIST OF THE 
fertilizers instead of stable manure. The difference in the me- 
chanical conditions of these soils is the apparent reason for the 
marked difference in the prevalence of tip-burn, the mechanical 
condition of the clay loam being much improved by the addition 
of the manure, while on the contrary, the liberal use of manure 
with the very sandy soil made a soil mixture which was so loose 
in texture that it did not produce good lettuce. 
Stable manure with commercial fertilizers.—The results which 
were obtained when commercial fertilizers were used instead of 
stable manure, having been set forth, the use of commercial ferti- 
lizers in addition to stable manure will now be considered. Soils 
9, 10, 11, 15, 16 and 17 each contained 33 1-3 per cent of stable 
manure. In addition to the manure, Soils 9, 10 and 11 received 
phosphoric acid, 600 pounds per acre, sulphate of potash, 400 
The 
average of the records for each of these soils are shown in the 
pounds per acre, and nitrate of soda, 366 pounds per acre.
