Cold-water Coils for Cooling Food 
A day or two ago, during a talk with 
a farmer neighbor, he told me that during 
last Summer his family got along nicely 
without the use of ice in taking care of 
their milk, cooked victuals, etc., by 
simply putting up a few shelves around 
the pressure tank of his cold water sup¬ 
ply. This put an idea iuto my head, and 
I wish you would tell me if my idea is 
practicable or not. When I built my 
present home, just outside the city, I 
arranged my plan to have a small room 
connected with the kitchen in which to 
place a refrigerator. The room is about 
24 in. deep by 54 in. wide, with a pair 
of doors opening at center into the kitchen. 
Knowing this small room to be on the 
“warm side” of the house. I had mineral 
wool well packed iuto the walls between 
the 2x4’s, so that we have never had any 
trouble on account of heat, even during 
hot Summers. We cannot always get ice 
handily, and it is expensive when we do 
get it. I also have a water supply through 
the house, fine cold water, coming from 
68 ft. deep, the pumping being done by 
means of an automatic electric pump, the 
water being forced into a small 30-gallon 
tank I happened to have and thence to 
the sink, closets, etc., in usual manner. 
its attendant rise in temperature before 
reaching the faucet—an undesirable con¬ 
dition. There would be a condensation 
on the pipes, but this could be caved for 
by troughs under the coils. The case 
would be entirely different from the 
shelves around the storage tank spoken 
of, for in this case the body of water 
was comparatively large and the tank 
itself was probably located in the base¬ 
ment or other cool place. R. H. s. 
Utilizing Small Water-power 
I have a never-failing spring that runs 
water enough to fill a 6-in. pipe. This 
spring is in a small gulley. By putting 
a dam across the mouth of gulley I can 
get a pond of about one-third acre and 
.five or six feet deep. Would a 6-in. pipe, 
say on a 20-degree angle, carry water 
enough to run a small turbine wheel? I 
would like to get about five horsepower, 
if possible, so as to be able to saw cord- 
wood for firewood. M. B.

Your statement that the spring fur¬ 
nishes water enough to fill a 6-in. pipe 
really gives no basis upon which to work.

is capable of developing the quantity of

Plan for Cooliny Food with Cold Wilier Coils 
I have thought for some time of putting 
in a large tank, to do away with the fre¬ 
quent pumping, on account of smallness 
of tank, and now have it in mind to 
carry the pipe, using, say a 2-in. pipe, 
a distance of about 11 ft. along under¬ 
neath the floor (the tank now hangs 
horizontally next to ceiling of basement, 
as in sketch), thence up into my refrig¬ 
erator room, with a system of coils run¬ 
ning around the three sides of the little 
room, thence back to the tank or house 
supply. Coils at side could be horizontal, 
thus affording supports for ends of 
shelves. By doing this my idea is to 
make the small room cool enough to 
serve as a refrigerator for the storing of 
eatables, etc. Would my scheme work, 
and would there be liability of much.con¬ 
densation of water on surface of pipes? 
I thought not, on account of the original 
coolness of the room, due to the insulated 
walls. I would expect to carry the coils 
to a height of say five to six ft. Would

The cooling of milk, butter and cooked 
foods on the farm is a subject that has 
been given considerable thought and 
numerous ingenious devices have been 
constructed for the purpose. I would not 
expect the arrangement proposed by J. 
B. B. to be satisfactory, however. Water 
as a cooling agent has not the capacity 
of heat absorption that ice has, and that 
is of course the method by which the 
cooling is accomplished—the heat is 
soaked up from the material to be cooled 
by the cooling medium in much the same 
way that water is soaked up by a sponge, 
leaving the material cool—heat has been 
removed from it. 
Ice in melting absorbs great quantities 
..f heat without having its temperature 
raised. It is still at 32 degrees F. until 
the last particle is melted. With water 
the case is different. The coldest of well 
or spring water will range from 40 to 45 
degrees F, in temperature and imme¬ 
diately it is brought in contact with any 
warmer body, as the warm air in the 
cooling room, its temperature begius to 
rise. This means that to get effective 
cooling from water the amount must be 
large and kept in circulation. In the 
case of the cooling room planned there 
would be but a small amount of water 
in the pipes, making the surface exposed 
to absorb heat small, and there would be 
no circulation. Even if both ends of the 
coil were connected iuto the main there 
would be little cause for circulation un¬ 
less the closet Hushes and all service 
faucets in the house were arranged to 
draw their supply of water through the 
coil. This would mean that the drinking 
water took its turn at cooling food with 
water available and the head or fall must 
be known, as water is capable of doing 
work by reason of its weight and position. 
The quantity can be determined when the 
velocity and cross-section of the stream 
are known, but can only be guessed at 
when it is -said, as in this case, that the 
water available will fill a certain size 
pipe. It is easily seen that with two 
pipes of equal size, if the velocity were 
twice as great in one as in the other, 
twice as much water would be discharged. 
If the water had a velocity of 3 ft. per 
second or 180 ft. per minute in the 6-iu. 
pipe spoken of. 35.343 cubic feet would 
be discharged per minute, and this falling 
a distance of 6 ft. would be capable of 
producing .40 horsepower. Probably not 
more than 70 to 80 per cent could be re¬ 
covered as useful work making from .28 
to .3. from about one-fourth to one-third 
horsepower all that could be expected. 
This would be sufficient to pump water 
and do light work, but could hardly bo 
expected to saw wood unless there is a 
great deal more water than you think. 
If the water could be carried farther down 
stream and a greater fall secured, a cor¬ 
respondingly greater power could be de¬ 
veloped from it. doubling the head or fall 
doubling the power obtained with a given 
quantity of water. With so small a water 
supply a wheel of the overshot type will 
give the best results. k. h. s.

Dynamite for Tree Planting 
I received my fruit trees April 23. Next 
day we took them up on my farm, five 
miles north, and planted them all in two 
days. My three boys helped me. They 
were 160 apple trees, four walnut, four 
pear, six cherry and two apricot. I had 
the places for these trees marked out be¬ 
fore; all are 45 ft. apart and in a line 
each way. We used Vi lb. dynamite for 
each hole, and it was just fun to see them 
blow out. It left the ground in the holes 
loose and mellow, like sawdust. We could 
run the shovel in almost the whole length. 
The ground is light, yellow clay. We shall 
not plow up this meadow, but we intend 
to put manure on top later on. and keep 
the weeds off. The rest of the dynamite 
we used to blow out some big stones, of 
which we have enough. w. F. a.

Own a Better Cultivator 
T3UY an International cultivator because it 
will cultivate cleaner and injure less corn. 
Look the machine over first and you will prove to 
your own satisfaction that the International is 
ahead of anything else on the market. 
The International line of cultivators is complete. It includes, 
besides the regular line of rigid cultivators, pivot pole and 
pivot axle machines with parallel gang movement, combina¬ 
tion riding and walking cultivators, two-row cultivators, motor 
and horse, and an excellent line of walking cultivators. Extra 
heavy gang equipment can be obtained for use in hard clay 
soils. A great variety of shovels is available, and sizes can be 
had from the 2-inch “Bull Tongue” to a S-inch corn plow. 
Study the wheels — the life of any farm machine. The 
rims are concave, the spokes are large and oval in shape to 
resist side thrust and cast solidly into the hub under tension. 
Every spoke supports its share of the load, and will stand up 
under the hillside work much longer than the average flimsy- 
cultivator wheel. 
International cultivators are light draft and easily handled. 
Any boy that can drive a team can climb on an International 
cultivator and do good clean work in the average cornfield.
