The above-named manures have given the best results as 

 applied to barley sown with grass seeds, where no farm-yard nor 

 city manure was used along with it. As I have already stated, 

 barley is very easily forced, and the difficulty is to do justice to 

 the succeeding crop of grass without forcing it too much. It 

 would be a simple enough matter on heavy soil, but is very 

 difficult on free light soils, where so much depends on the stimu- 

 lants and the season. 



Any of the five mixtures of manures I have named do very 

 well, but I would give preference to the first two, and between 

 them it is merely a matter of cost. The third and fourth on the 

 list do not generally insure so heavy a crop on an average of 

 seasons, being more especially deficient in a cold wet spring, but 

 both of them grow the grain of very good quahty. The fifth, on 

 an average of three seasons when I used it, did not turn out very 

 satisfactorily, either for grain or first year's grass. The barley, 

 although starting very well, grew too soft in the straw, and not 

 so good a quality of gTain. With all my experiments with bone 

 meal, I have come to the conclusion that it does far less good the 

 first season than is generally supposed, the phosphates and 

 ammonia not becoming available as plant food nearly so soon as 

 where treated with sulphuric acid. The first four mixtures have 

 given results nearly alike on an average of seasons so far as grass 

 is concerned, and the barley grown with these manures, as com- 

 pared with the unmanured plot, was in several seasons double 

 that grown without manure, and even when the unmanured 

 portion came closest up there was margin enough left to pay the 

 artificial manure applied twice over. In fact, my firm conviction
