jq'o. 5, — 255 lbs. pure Peruvian guano, mixed with 11-2 

 horse-carts of brook mud. 



The cost or value of the top-dressing, for each lot, was as 

 near ten dollars as possible. The grass was very carefully cut 

 and made — the first crop in July, the second in September — 

 and accurately weighed, yielding as follows : —

You are aware the early spring was very dry, and quite a 

 drought prevailed during the months of April and May. This 

 no doubt retarded vegetation, and checked, particularly, the 

 fertilizing qualities of the ashes, as they laid in the sward for 

 a length of time as dry as when first spread. The copious 

 rains afterwards produced a wonderful change in thickening 

 up of the grass. The guano dressing, you will observe, pro- 

 duced much the largest quantity on the first crop, although 

 very little more than the green cow manure with the aggregate 

 of both crops. 



The second mowing of the guano lot disappointed me, and 

 its short comings on the second crop almost conclusively proved 

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

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

 on the return of the next season, to find the green cow ma- 

 nure 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."
