Jbteign Agricultural Nzm. 
By the steamer Canada, we are in receipt of our for¬ 
eign journals to the 9th of August. 
Markets. — Ashes, lower. Cotton, an advance of 
per pound. Flour and Grain, heavy sales. Pro¬ 
visions, generally dull. 
Proportion of Carbonic Acid Endured by Healthy 
Plants. —The result of the late investigations of Dr. 
Daubeny, of England, prove that 10 per cent, of car¬ 
bonic acid is not at all injurious to plants, and that it 
is some time before even rather larger proportions of 
that gas begin to produce bad effects. Even as much 
as 20 per cent, produced no injury in ten days.— Gar¬ 
deners' Chronicle. 
Cost of the Conveyance of Sewerage Water. —It is 
calculated by experienced engineers, that sewerage 
water may be raised by the steam engine 150 feet, 
and forced through iron pipes in the way the supplies 
of water are brought to most large towns, and thus 
conveyed and sold with a profit at 2 %d. the ton, after 
being conducted in this manner 14 miles.— Agricultural 
Gazette. 
Bone Manure Consumed in England. —England 
consumes more bones, for agricultural purposes, than 
all the rest of the world. As bones gathered for 
this purpose in Great Britain are free from police or 
excise inspection, we have no means of ascertaining the 
amount of the home supply; but the official value of 
those imported amounted, some 12 years ago, to 
$1,500,000 per annum, and the selling price to our farm 
ers would probably be little under $2,000,000. Since 
then, the foreign supply has been decreasing; the 
bones imported in 1848 being worth, in bone dust at 
31 cents per bushel, about $1,100,000.— Scottish Jour, 
of Agriculture. 
Increase of the Use of Guano in England. —The 
imports of guano rose from 2,000 tons in 1841, to 220- 
000 tons in 1845 ; but since then, the paucity of the 
supply has caused the average annual importation to 
fall to about 90,000 tons. It will give some idea of 
the energy and enterprise of our farmers to state that 
as the price of guano has ranged from $30 to $50 per 
ton, the money expended on the purchase of this ma¬ 
nure alone amounted, in 1845, to the enormous sum of 
a million and a half sterling.— Ibid. 
Depdts of Lime and Gypsum for Farmers. —The 
Belgian government, having established depdts in dif¬ 
ferent places throughout Luxemburg and Namur, for 
supplying lime to the farmers of those districts, in 
which it had been very difficult for them to obtain that 
earth, for the improvement of their land, have, by a 
further measure, ordered the establishment of depdts 
of gypsum in different parts of Flanders for the same 
purpose, a substance which, although most cheap and 
abundant in France, is not found naturally in Belgium, 
in any working quantities.— Ibid. 
Re-appearance of the Potato Disease in Ireland .— 
Reports concerning the re-appcarance of the potato 
disease have again become rife. Irish newspapers, in 
particular, speak of unrnistakeable evidence having 
been obtained of the renewal of the plague spot; and 
our own correspondents have, here and there, an¬ 
nounced the same fact. That we should see such 
symptoms for some years to come is the least that can 
be expected; for a disease like that in question is not 
likely to disappear as rapidly as it came on. But we 
are happy to be able to allay such apprehensions as 
exist, by stating that after diligent inquiry we can hear 
of nothing which ought to excite alarm; and that we 
believe the crop to be just as safe as it was last 
year.— Ay. Gazette. 
Grape Mildew in France. —M. Bergman, junior, gar¬ 
dener to Baron James de Rothschild communicates the 
following to the editor of the London Gardeners’ 
Chronicle:—“I beg to send you a specimen of the 
kind of mildew which has infested vines both in houses 
and in the open air, in the vicinity of Paris during these 
three years past, and principally in the gardens of 
Versailles, Suresne, and Ferrieres. In these places, all 
possible means have been employed to avert the mala¬ 
dy, but without success. Sulphur, tobacco smoke, 
tar water, and lime water, have been used, but the 
parasite makes new progress every day, and the grapes 
are rendered uneatable. I hope you will be able to 
furnish us with some new expedient for combating the 
epidemic. [You had better provide yourself with one 
of the modern sulphurators. Sulphur applied early 
enough, and presevered in, is a certain cure in this 
country. But you must persevere, and you must at¬ 
tack the enemy when he first appears.”— Eds.] 
The Supply of Peruvian Guano. —-The agency in 
London have just published an account rendered by 
Messrs. Antony Gibbs and sons, to Messrs. Rivero and 
Murrietta, the commissioners for the Anglo-Peruvian 
debt, of the quantity of guano sold in this country. It 
appears from this that the total imports have been 
130,580 tons, of which the sales already accounted for 
have been 50,233 tons, the sales subsequently effected 
and to be accounted for hereafter have been 31,661 
tons, and the stock on hand unsold on the 30th June, 
amounted to 42,68fi tons. In the 50,233 tons sold the 
proceeds have been £212,546 Is. 3d. giving an average 
of £4 4s. the price to be received for the 37,661 
tons of which the sales have been subsequently effected. 
The result of these returns is, that £107,200, being 
half the net proceeds, after deducting the amounts paid 
for former dividends, has been applied to the reduction 
of the Peruvian debt. The report of the agents states 
that “ the quantity of guano which will have arrived with¬ 
in the ensuing 12 months will not be less than 150,000 
tons; that the demand for the guano is not only in¬ 
creased in this country, but also in all other parts of 
the world; that the guano on the Chincha Islands is 
inexhaustible, and from the peculiar nature of these 
rainless islands it is not likely that any other guano 
will be discovered elsewhere retaining the ammonia, 
which constitutes the pre-eminent value of Peruvian 
guano.”— Agricultural Gazette.
