I hereby certify, that I have used this season, some of the chemi¬ 
cal guano, manufactured by D. B. Stockholm, Esq., on potatoes and 
cucumbers with decided success. Both were planted the fifth day 
of May, and by the fourth of July, T have potatoes on the parts 
manured, of good size and fit to boil; whilst the next row of pota¬ 
toes which was not manured with the guano, have none larger than 
peas; my cucumbers were also large enough for the table by the 
fourth of July. The vines grew vigorously; were of a dark color; 
their stems were the largest I ever saw, they lasted long, and yield¬ 
ed an abundance of fruit. My garden adjoins that of Mr. Stock¬ 
holm, where he has also been making experiments with his guano, 
and I have noticed them particularly at his request. 
Corn manured with it liberally, planted the last of May, although 
it was injured by the drought, grew vigorously. It is now well 
eared and out of danger of frost. 
Some corn planted the first of July, to which the manure was ap¬ 
plied, has also grown well, although hoed bui. once; and now has 
on it cars nearly fit to roast. The beets, carrots and melons have 
also grown luxuriantly, although in consequence of the frequent 
absence of Mr. Stockholm from the village during the summer, the 
garden has been neglected, and is overrun with weeds and grass. I 
am well satisfied that the vegetables of his garden have not been 
better, if as well attended as the corn of the farm grown in the field. 
This was done intentionally by Mr. S. in order that he might ascer¬ 
tain -what would be the probable effect of the manure upon the crops 
of the farmer. The garden of Mr. S. had no other manure this 
season; but the guano was liberally applied twice to the corn. It 
is of full height, its color is dark, and for the kind of corn, (Tusca- 
rora and sweet corn) the ears are numerous and of good size. It 
is planted in hills about 2J feet apart. 
I have closely observed with much interest, the effect of this new 
manure, and have no hesitation in saying, that the chemical guano, 
discovered by Mr. Stockholm, is the greatest and best manure I ever 
saw. . • 
From the corn planted the first of July, was gathered on the 11th 
of September, a mess of corn fit to boil; and if we have no frost 
before the 16th it will ripen.
