MANURES.

that it had lost much of its fertilizing properties in the produc- 

 tion of the first crop of grass. It would not surprise me, on 

 the return of the next season, to find the green cow-manure lot 

 superior, and more reliable, than either of the other fertilizers 

 as a general dressing. Should the return of the next year's 

 mowing result as I anticipate, I may possibly trespass upon 

 your valuable paper at a future day." 



Having given the statement of 1860, I now proceed to show 

 the results of the present season, wishing it to be distinctly 

 understood that no additional top-dressing of any kind has 

 been applied since the spring of 1860 : — 



In order to show this year's results, the stakes were very 

 carefully preserved, and great care observed in mowing the 

 several lots, and especially as to the true weight of each. It 

 will be observed that the difference in yield of the aggregates 

 of 1860 and 1861, is very small — the former being 7,010 

 pounds, the latter 7,000 pounds, and yet it will be perceived 

 that there is a great difference in the results of the several 

 fertilizers used in these experiments ; but when looked at sepa- 

 rately, this difference is satisfactorily accounted for. 



Having already given a statement of last year's results, as 

 well as those of this year, I shall now confine ray remarks 

 principally to show where this difference happens. On looking 

 over the results, it will be found mainly in the falling off of the 

 guano-dressed lot, and in the great increase in the ashes lots ; 

 for the guano lot gave this season, on its first cutting, only
