we simply give the accompanying engraving 
showing its form, with directions for laying it 
out upon the sides of the wheel. The engrav- 
ing represents the circumference of the wheel 
with the shrouding which forms the sides of 
the buckets. This shrouding should be divided 
into three equal parts, which the one included 
between the inner circle and the dotted line 
a, a will be equal to the length of the starts or 
soles of the buckets, b, b. These should be laid 
out in the direction of radii from the center or 
the axis of the wheel, as shown by the dotted 
lines c, c. These lines or radii should be car- 
ried out to the outer circumference of the 
shrouding, as seen in the lines c, c in figure 1. 
The flats of the buckets should then be laid out 
from the extremity of the starts or soles to the 
point where the preceding lines touch the cir- 
cumference, as seen in the dark lints c, c. The

lines should coincide with the number of buck- 
ets desired. For these no particular rule can 
be laid down in these cases, as they will depend 
upon the length of the buckets and the quantity 
of water to be used. This form of bucket 
meets the chief requirements of cases where the

greatest economy of water is not an object, and 
will answer every purpose where it is not de- 
sirable to employ a skilled millwright. To en- 
able the water to leave the wheel promptly 
when it runs iu tail water a valve or valves of 
leather weighted with sheet-lead may be affixed 
to the soles of the buckets, as shown at 6, fig.l. 
As the buckets rise out of the tail water these 
valves will open and admit air, which will 
cause the water to escape at once. This simple 
contrivance has very much increased the power 
of a wooden wheel to which it has been applied. 
The way in which the valves are applied to the 
soles of the buckets is shown in fig. 2. They 
are self-acting, as will be readily understood. 
Portable Fence for Poultry Yard. 
" E. B.," Ann Arbor, Mich., asks for a port- 
able fence for a poultry yard. Such a fence 
may be constructed as follows : A post three 
inches square may be driven or set in the 
ground and braced, as in the accompanying en- 
graving, fig. 1. This post is provided with two 
hooks similar to those upon which gates are 
hung. Bars of light stuff, which need not to be

heavier than 1| inch thick by 2 inches wide, 
are then provided of such a length as the pan- 
els may be desired (see a, fig. 2). These bars 
are furnished with eyes at each end, which fit 
hooks upon the posts. They are also grooved 
at such distances apart as the pickets are to be 
placed, or say four inches. The grooves are 
cut half an inch deep, and large enough to 
allow a 34-inch nail to lie in them aud no more. 
The pickets (b, fig. 2) may be made one inch 
square, and as loug as may be desired. If the 
poultry are heavy-bodied birds, five feet will be 
enough, as also if the birds are light and have 
the wings cut. These pickets are bored with 
holes to receive a 34-inch nail, either wrought 
nails or cut nails which have been annealed. 
The nails are driven through the pickets in the 
proper places, and as the pickets are placed in 
position the nails occupy the grooves in the 
bars. The points of the nails are then turned 
down, forming hooks by which the pickets are 
kept in their places. When t!ie fence is to be 
moved it may be taken apart and set up in an- 
other place with great facility. Fig. 3 shows 
a panel of the fence as completed. 
Black-Leg ln Calves. — "J.W. R.," Green- 
castle, Ind. In the spring or the fall, when thei 
feed is changed either from dry to green or 
from green to dry, it is not uncommon for 
calves and young cattle to be affected with a 
very rapidly fatal disease known as black leg. 
First lameness is noticed in the fore or hind, 
but generally the hind cruarters ; the eyes are 
bloodshot, and the mouth and tongue are hot 
and blistered. The swellings crackle as the 
hands are passed over them, and after death, 
which is generally very rapid, the flesh beneath 
the swollen parts is black and suffused with 
readily be prevented by care at this season. 
Towards the approach of spring the young 
animals should be given a pound of linseed- 
cake meal daily, and the condition of the 
bowels should be watched. If the dung is 
hard, and covered with slime or mucus, a few 
ounces of Epsom salts should be given ; whea 
the animals are turned out in the spring to 
grass it should be for an hour or two only at a 
time for a few days; and the first appearance 
of fever should be treated with a brisk purge. 
Plan for a Commodious Sam. 
W. P., Benton, Grafton Co., N. II., sends us 
plans and description of a barn built by him 
upon a farm of 130 acres upon which mixed 
fanning is practiced. 
The main building is 
108 feet long by 40 feet 
wide, with 20-fect posts. 
The wing at the right is 
82 feet long by 30 feet 
wide, with 15-feet posts. 
The left wing is 40 feet 
long by 16 feet wide 
with 12-feet posts. 
There is a cellar under 
the main barn 10 feet 
deep, 80 feet long, and 
40 feet wide. As is seen 
by the engraving, figure 
I, which shows the elevation, the barn is built 
upon a hill-side, with three stories. The main 
floor.of which figure 2 shows the plan, is reached 
by a bridge (B) which inclines two inches to the 
foot. A is the main floor; G,G,0 are bays; 
D, D are shoots to the granary ; E, E are stairs 
to the floor below ; F, F, F are hay shoots to 
the horse stables ; G, O, store rooms for wool ; 
II, chimney, with an 8-inch wall and two flues, 
one of which is for ventilation. 
Figure 3 shows the floor containing horse 
stalls, feed and cook rooms, repair and work 
rooms, milk room, and shoots for feeding the
