tween 32° and 50° F. ; but if the climate be such 
as to expose them to freezing cold, as in most parts 
of the Middle and Northern States, the heaps must 
be more thickly covered either with earth or straw. 
Another plan of storing which we have known 
to succeed well in some parts of New England, is 
to bury the turnips late in the fall, in a dry, gravelly, 
or well-drained soil, just below the reach of frost, 
and in the April following, we have seen them dug 
up in nearly as hard, and sound a condition as at 
the time they were stored. The main and absolutely 
necessary points to be observed in this mode of stor¬ 
ing, is, to keep the turnips secure from wet, or frost, 
and as near as possible to a temperature of 32° F., 
which, if it cannot be done by the natural porosity of 
the soil, must be affected by under-draining and inter¬ 
mixing them with reeds, straw, or hemlock boughs. 
CORN AND COFFEE-MILLS.- 
It has long been a great desideratum to such as 
do not reside convenient to a mill, and to those 
who only wish now and then to grind a mess of 
.hommony or some such trifling thing, as well as to 
travellers and armies on the march, in a thinly set¬ 
tled or savage country, to possess a mill of so light 
a weight and convenient form, as to be easily 
transportable, yet strong, durable, and of simple 
construction. This desideratum we think has been 
attained in the mills described below, which will be 
found suitable for grinding rice, corn, wheat, rye, 
barley, oats or any other kind of grain into meal; 
but they do not flour wheat and rye well, because 
they cut the grain with their iron teeth instead of 
mashing it between stones. For this reason they 
are better than stones for corn, and equally good 
for all kinds of grain, when flouring it for market 
is not desired. They are also suitable for grinding 
coffee and spices of all kinds. 
These mills are made of plates of dast iron, and 
will usually last to grind from 500 to 1000 bushels 
of grain. After being worn out, new plates can be 
supplied, which will grind an equal number of 
bushels. The grain or spice, when put into these 
mills, falls from the hopper among coarse teeth set on 
a spiral shaft, which, in revolving rapidly, break it 
coarsely, and then pass it in between plates which can 
be screwed up to grind it to any required fineness. 
Fig. 63. 
Fig 63 is properly a coffee or spice-mill, but will 
grind grain of any kind. It is sold without a frame, 
and is so constructed as to be fastened to a post or 
board in any part of the house, or it can be attach¬ 
ed to a simple frame. It grinds from eight to six¬ 
teen quarts per hour depending mainly on the speed 
at which it is run. Weight, 10 lbs. Price $2. 
Price of extra plates 50 cents. 
Fig. 64. 
Fig. 64 is used for grinding grain, coffee, and 
spices, as desired. It is usually operated by hand, 
though it can be constructed to run by other power. 
It grinds from one to two bushels per hour. Weight 
without the frame, 50 lbs.; wflth the frame, 64 lbs. 
Price, without frame, $6.50; with frame, $7.00. 
Constructed to move by horse or other power, the 
price with frame complete would be $9.00. Price 
of extra plates, $1.25. 
Fig. 65. 
Fig. 65 is used for the same purposes as Fig. 64. 
It is too large to be propelled by hand to advantage. 
Weight without the frame, 190 lbs. ; with the frame, 
221 lbs. Price without the frame, $29 ; with frame, 
$30. Price of extra plates per pair, $4.
