Analyses of Soils, Manures, &c.“-From the fre* 
quent inquiries which have been made, in regard to pro¬ 
curing reliable analyses of various substances, the offi¬ 
cers of the New-York State Agricultural Society, have 
been induced to make an arrangement with Dr. J. H. 
Salisbury, by which investigations may be obtained in 
the various branches of agriculture which practical 
chemistry is capable of illustrating. The charges for 
analysis are as follows: 
Complete quantitative inorganic analysis of.a soil, limerock, 
gypsum, peat, marl, animal manure,... $5 00 
Complete proximate organic analysis of a manure, marl, peat, 
, soil,............ 5 00 
Determination of the per centage of water, dry matter, and 
ash in manures, &c..... 2 00 
Analysis of mineral or spring waters,.. 7 00 
The above fees to accompany all samples or communications. No 
analysis will be allowed to pass out of the Laboratory till paid for. 
The .analysis of ores, minerals, rocks, commercial articles, &c., 
also attended to with care. 
For analysis, enough of the above substances should be sent to 
make half a pound when dry. Of mineral or spring waters, about 
one gallon is required. 
Samples and communications may be forwarded, post 
paid to Dr. J. H. Salisbury, or to B. P. Johnson, Esq., 
Secretary N. Y. State Ag. Soc., old State Hall, Albany. 
Stanley and Dickerman’s Indian Portrait Gal¬ 
lery. —Having had the pleasure of examining this 
splendid collection of Indian portraits, while it was being 
exhibited in this city, we feel that by calling attention 
to it, we may perform a public service. It consists of up¬ 
wards of one hundred figures, sketched from life by 
Mr. Stanley, during a sojourn of several years among 
the various Indian tribes between the Mississippi river 
and the Pacific ocean. They represent almost every 
phase of Indian character, from the wild and supersti¬ 
tious Pawnee-Pict, to the civilized and intelligent Chero¬ 
kee. ¥e have good reason to believe that these fig¬ 
ures are likenesses, and they are, besides, declared by 
connoisseurs to possess much artistic merit. Great 
credit is due to Messrs. S. and D., for the unwearied 
pains they have taken in producing this collection. The 
Indian, as he was by nature, is rapidly passing away, 
and in a short time he will be seen only as changed, 
more or less, by intercourse with the race by whom he 
has been supplanted, and before whom he seems des¬ 
tined to yield the last foot of that vast territory over 
which he once roamed. 
Multicole Rye. —E. G. Booth, states in the South¬ 
ern Planter that he has tried this variety of rye in com¬ 
parison with other varieties, on several kinds of soil, and 
in all cases the Multicole was superior in yield—on some 
rather poor soils, it yielded twice as much as any other. 
Bones as Manure.' —The use of bones as manure was 
commenced in England, about 1776. It was then com¬ 
mon to apply from 60 to 70 and even 100 bushels to the 
acre—they being coarsely broken by hammers. Ex¬ 
perience has proved, however, that so large a quanitty 
does not produce effects in proportion, and 10 to 12 
bushels are now thought to be sufficient in most cases. 
The annual value of bones used in England for manure, 
is estimated at £880,000 or $4,400,000. 
World’s Exhibition for 1851.—We learn from the 
English papers that the arrangements for this great ex¬ 
hibition are progressing rapidly. The stupendous 
building, destined to receive the numerous articles which 
will be sent from all parts of the globe, will probably be 
completed by the appointed time. 
The exhibition is to be opened in Hyde Park, London, 
on the first day of May, 1851. Goods will be received 
between the first of January and the first of March,— 
after the latter day, none will be received. The build¬ 
ing is to be 1,848 feet long, 408 feet wide, and 88 high, 
with a machinery room 936 feet long and 48 feet wide. 
It is to be chiefly of cast-iron and plate-glass 3 4,000 
tons of the latter material will be required for the 
roof. An avenue, 72 feet in width, extends lengthwise 
through the center of the building. Along the sides 
of this avenue, at distances of 24 feet, are placed co¬ 
lumns, for the support of the roof. Girders of iron are 
inserted into the sides of the building and the columns, 
18 feet from the floor. These girders are two feet in 
depth, and 2,244 of them will be required. The strength 
of these girders, and of every piece of iron used in the 
building, is tested by a powerful hydraulic press. A 
transept crosses the main building near its center. The 
transept is to have a circular roof, which is to rise 20 
feet above the other part of the building, and cover a 
row of six very large elm trees, around which it is in¬ 
tended to provide a first-class refreshment room. The 
length of the transept, including the space to be set 
apart for refreshment rooms, will be 408 feet, its width 
72 feet, and the height from the floor to the center of 
the circular roof will be 108 feet. 
To PREVENT THE ATTACK OF THE “ ONION GrUB.”—• 
The growth of the onion is frequently prevented and the 
plant sometimes destroyed by a worm which attacks it 
as soon as it appears above ground. A correspondent 
of the Gardener’s Chronicle states that he has applied 
nitrate of soda with good effects in preventing the rava¬ 
ges of this insect. He used half a pound of the salt to 
a gallon of water, and applied eight gallons to a bed of 
ten yards in length. He states that it checked the pro¬ 
gress of the worms, and the crop turned out well. 
Average Products of an English Farm. —The fol¬ 
lowing are the averages of some of the products of a 
farm of 740 acres, near Brighton, England, occupied by 
Wm. Rigden. He has 250 acres of wheat, averaging 
26 bushels per acre 3 40 of barley, 40 bushels • 60 in oats. 
60 to 80 bushels 5 240 acres in clover and grasses, two 
tons hay. He keeps 350 South Down ewes, which ave¬ 
rage yearly about 400 lambs 3 average quantity of wool 
yielded by the flock, four pounds per fleece, and it sells 
at 25 cents per lb. He keeps 21 cows, which yield on 
an average ten quarts of milk per day, the year round. 
Height of Lightning Rods. —It has been laid down 
as a rule, derived from experiments made in France, on 
the conducting power of lightning-rods, that a rod will 
protect a circle whose radius is equal to twice the height 
of the rod. Prof. Loomis, of Mew-Haven, states that
