A Movable Wire Fence. 
A year ago this month, we gave an illustration 
of a fence of wood and wire — called a Prairie 
Fence — invented by Thomas H. Speakman, of 
Philadelphia. Since then highly favorable re- 
ports have been made upon it by committees of 
the Delaware County Institute of Science, in 
which county is the farm of the inventor, and 
the Agricultural Society of Philadelphia, where 
he resides. Inquiry having been made for a 
movable reuce, Mr. Speakrnan turned his atteu- 
bolts, and may be readily carried from place to 
place by laying the panels on a couple of six- 
teen feet boards, on a cart or wagon. It is es- 
timated to cost about the same as the perma- 
nent fence before alluded to, and fully one third 
less than the wooden fences iii ordinary use. 
To answer inquiries in advance, we will say that 
the fence is patented by the inventor. 
Guano— As Sold in New York. 
To the Executive Committee of the New York State 
Agricultural Society: 
The undersigned having been appointed a 
Chemical Committee under the resolution of 
the Executive Committee passed May 4th, 1872, 
and instructed to obtain samples of guanos sold 
at retail in the city of New York, and to have 
them analyzed by Mr. William M. Habirshaw 
(analyst to the chemical trade of that city), who 
Co., the agents of the Peruvian Government in 
New York City, a bag of Guanape Guano, num- 
bered 11, and of the Manhattan Manufacturing 
and Fertilizing Company, a bag of their nitro- 
genized superphosphate, sold under the name 
of Phosphatic Blood Guano, numbered 12 in 
this report. 
That the several hags so purchased were con- 
veyed to the residence of Mr. Cocks as speedily 
and directly as possible, and there carefully 
sampled by your committee, the samples put 
into sealed glass jars and numbered I to XII (1 
to 12), as above, and delivered to Mr. Habirshaw 
for analysis. 
That on the 21st day of October they received 
the report and analyses of the said 12 samples 
from Mr. Habirshaw, as given in the accom- 
panying table, dated New York City, October 
10th, 1872. 
For the purpose of showing how largely the 
several samples vary in value, we append the 
tion to that, and the result is shown in the illus- 
tration. The fence consists of four separate 
parts — 1. The end or straining posts; 2d. The 
triangular horses which fill the places of inter- 
mediate posts; 3d. The panels, sixteen feet 
long, made of wire and wood as shown; and 
4th. Common half-inch screw-bolls, by which 
all the other parts are secured together. 
The manner of putting it up, is first to anchor 
one of the straining posts to the ground at the 
starting point, by fastening it with wire or a 
chain to a stake firmly set in the ground, as 
represented at the right of the cut. The first 
panel is then bolted to this post and the forward 
end of it connected to the second panel hy two 
bolts, which pass also through the horse; the 
nuts being only screwed up their own thickness. 
Tiie panels are then set up one after another in 
the same way — being drawn as tight as they can 
be by baud, and temporarily propped at inter- 
vals, to retain the tension thus gained. When 
the farther end is reached, connection is made 
to the other end post, which is anchored to the 
ground the same as the first. The wires are 
then tightened at pleasure by screwing up as 
many of the nuts as may be necessary. 
This fence is effective and can not blow over. 
Any number of strands of wire may be used, ac- 
cording to Use kind of stock to be stopped. It 
IB readily taken .apart by undoing the screw-

had offered his services to the Society for this 
investigation, respectfully report : 
That they caused to be purchased of each of 
the dealers and firms named below, one bag of 
guano at the dates and prices below stated, and 
numbered the same as below, the same num- 
bers being referred to in the analyses given in 
this report : 
Aug. G, 1872.— 1. Robert C. Reeve?, 183 and 1S7 Water 
»t., 1 bag guano, 170 lbs., $6.37. 
Aug. 9, 1S72.— 2. E. H. Reeves & Co., 184 and 195 Water 
st., 185 lbs. guano, $0.04. 
Aug. 6, 1S72.— 3. Decatur & Coxe, 197 Water St., 179 lbs. 
guano. 3 3 ^c. $0.72. 
Aug. 9, 1S72. — 1. Geo. Ricardo, 195 Waterst., lbag guano, 
1781bs.,at.3i£c, $6.67. 
Aug. 6, 1872.— 5. Vafidcrbilt Brothers, 53 Fulton st., 1 bag 
Peruvian guano, 162 lbs., at 8j£C, $6.07. 
Aug. 6, 1872. — 6. John Moore, 193 Front St., 1 bag guano, 
161 lbs.. $6.04. 
Aug. 6, 1872.— 7. E. A. Reeves, 53 and 60 Cortliudt St., 
1 bag No. 1 reruvian guauo, 197 lbs., at 4c., $7.8S. 
July 23, 1S72.— 8. R. H. Allen & Co., IS9 and 191 Water 
st., 1 bag guano, 170 lbs., at 4c, $6.80. 
July 26, 1872.— 9. Chapman & Van Wyck, 170 Front St., 
1 bag No. 1 Peruvian guano, 16S lbs., at $75 per ton, 
$6.30. 
Aug. 9, 1872.— 10. George E. White, 160 Front St., 1 bag 
No. 1 Peruvian Chincha, 180 lbs., atdc., $7.20. 
That these purchases were all made by Mr. 
Cocks, of your committee, and shipped to his 
farm at Old Westbury, L. I., by railroad. 
That for purposes of comparison your com- 
mittee obtained of Messrs. Hobson, Hurtado & 
following results of a computation in which it 
was assumed that the value of nitrogen is 17 
cents in gold per lb., and of phosphoric acid 10 
cents in gold per lb., and that no other constitu- 
ents should be taken into account. The values 
were thus computed for each of the samples, 
I to XI, per ton of 2,000 lbs., and are (in gold) 
as follows: 
No. of sample. I. H. III. IV. V. VI. 
Value .$32.97 $24.78 $33.28 $33.56 $69.00 $65.99 
No. of sample. VII. VIII. IX. X. XI. 
Value $42.35 $54.44 $54.60 $31.74 $66.75 
We desire to be clearly understood that these 
results as regards manorial values are given 
merely for the sake of enabling persons who 
may take an interest in the subject to compare 
the results above given ; and that it is not in- 
tended by your* committee to assert that the as- 
sumed standard of values or method of compu- 
tation is correct — still less that the figures given 
represent the true or even the approximate value 
to the farmer of the several samples. 
Your committee further report that their ex- 
penses hare been $75.30 for purchase of sam- 
ples, and that their account for the same 
has been paid by the treasurer ; also, $8 travel- 
ing expenses of Mr. Gould, not yet paid.
