It is very important to ascertain the quantity of water that flows in a
stream, and the head and fall, to determine the exact amount of power
and the work it is capable of doing. It is frequently the case that
mills are constructed before finding the power of the stream, and upon
trial are found to fall short of their calculations. We give a very
plain way which will determine this. Place a wide board as a dam across
the stream (called a weir.) When the quantity of water is considerable,
it must be made in sections to get it sufficiently wide and long; then
cut a notch as shown in the engraving and about two-thirds the width of
the stream, placing the bottom of the notch level, and let the ends of
the weir dam (B B) be well bedded on each side of the stream. Observe in
cutting the opening or notch to bevel the edges down stream to within
say ⅛ of an inch of the side up stream; that the edges of the notch
sides and bottom be almost sharp but true and square, and the whole
opening sufficient for the water to pass; the bottom of the notch can be
leveled by letting the water pass over in a thin sheet; then drive a
stake three to four feet above the dam to one side or the middle of the
stream, and the upper end of it on a level with the bottom of the notch
in weir. And now that you have the dam made and in position so that all
the water will pass through the notch and no leaks, allow the water to
reach its full depth, then take square or rule and measure the exact
distance from the top of the stake driven in the stream to the top of
the water flowing towards the weir; 2d. Width of notch; 3d. Head and
fall, and send to us, and we will give you the power of your stream,
size of wheel to do the desired labor, &c.

STEAM ENGINES.
Careful experiments and practice with a view to properly proportion the
motive power to the work to be done has prepared us for giving valuable
information concerning steam engines for the purpose of flouring mills.
And when requested will furnish the engines themselves combining the
necessary qualities, and see in person that all the parts, speed, &c.,
&c., be exactly adapted to do the work. When we furnish the engine, with
the other supplies of the mill, which is frequently the case, our
customers may rest assured all will be satisfactory as regards style of
finish, durability, sufficiency of power, and economy in the use of
fuel. We do not make engines ourselves, but purchase them of the best
makers, and if we should be consulted in all cases of whom to buy,
style, kind, &c., or be ordered to supply the engine direct, our
customers will be more likely to get what is best.
