METALS AND THEIR ORES. é 23 
fact that finely divided materials have the power of absorbing moisture 
from the air; but such unscientific statements as appeared in the testi- 
monials foreshadowed the withdrawal of the substance to serve for a fer- 
tilizer. The following extracts will illustrate: 
Dear Sir: I very gladly write you a statement of the effects of the ‘‘ Grafton Fertil- 
izer” as seen in my garden. Two quarts of ‘‘ Fertilizer” were placed about the roots of 
a grape-vine which had never borne more than a plateful. It is covered with bunches 
of fruit now of a very large size, which will ripen much earlier than usual. I think the 
chemical properties contained in this ‘‘ Fertilizer” will serve to hasten the period of 
ripening of all fruits and vegetables. Melons, cucumbers, and squashes flourish finely 
under its influence. Last year the vines were riddled by the striped bug; this season, 
when they appeared, handfuls of the ‘‘Fertilizer” were scattered over the vines, and 
they rapidly ‘‘vamoosed the ranch.” Not one bug remained! We gathered the first 
cucumbers grown in the town. Melon vines are a mass of yellow blossoms and green 
fruit, and they are not usually prolific so far north. 
The “Fertilizer” is death to all the insect tribe. Carbonic acid is fatal to animal 
life, while it is highly essential to the growth of the vegetable world. The ‘Grafton 
Fertilizer” possesses 32.11 per cent. of this desirable constituent,—solidified,—which, 
added to the lime, protoxide of iron, and silica contained therein, must prove one of 
the most valuable mixtures hitherto discovered. 
For peach-trees, it will undoubtedly be of eminent service. The peach borer can, by 
its aid, be driven from its haunts, and the pear-blight remedied. 
The success of-this fertilizer led E. C. Stevens, of Lisbon, to provide 
a similar material from Lyman, which also had a considerable sale. An 
analysis of it shows it to contain,—Silica, 90.60; lime, 3.27; sesquioxide 
of iron, 3.06; alumina, .31; magnesia, .38; carbonic acid, 1.35; water, 
1.06; alkalies, a trace; gold, a trace. 
GOLD IN THE SULPHURETS. 
Scarcely any topic connected with mining in New Hampshire is of 
greater practical value than the presence of gold in the various sulphu- 
rets, particularly those utilized for the extraction of lead or copper. It 
may frequently be the case that the expenses of mining will be just about 
met by the sales of copper or lead, with little or no margin for profit. 
Should it appear that gold or silver may also be extracted from these 
ores, this fact may insure a profit where otherwise none could be obtained. 
In other auriferous districts, gold is often obtained in abundance from 
sulphurets, and requires peculiar processes for its extraction. I have
