Edwin Taylor: I have had a little experience in that line. I fenced
around a twenty-acre orchard, expecting to combine horticulture and
agriculture right there. My hogs were lousy, and they did rub the trees,
and whenever they rub they destroy. Anybody who tries it will find they
will absolutely squeal for something to eat when there are bushels of
apples on the ground. I was at large expense to fence, but was so
disappointed with the hog business that I took the fence down.

COLD STORAGE.

By GEO. RICHARDSON, of Leavenworth, Kan.

It has been well said that "Necessity is the mother of invention." Cold
storage of the present time is understood as "mechanical refrigeration,"
and in general, the preservation of perishable articles by means of low
temperature, hence, the act of reducing the temperature of any body, or
maintaining the same below the temperature of the atmosphere, is called
refrigeration, or more familiarly known as cold storage, produced by the
employment of machinery of various types. Of those mostly in use, are
the compression system, using anhydrous ammonia as a refrigerant, by
expanding the ammonia either directly through coils of pipe arranged in
the storage rooms, or through coils of pipe that are submerged in salt
brine, where the brine is reduced to a low temperature and then forced
and circulated through pipes in the storage rooms, one being known as
direct expansion, the other, brine circulation, but both accomplish same
results.

To utilize anhydrous ammonia requires complicated and expensive
machinery, and to those not acquainted with the subject it may seem
strange that more units of heat are produced by the burning of coal,
wood or oil than there are units of cold produced to reduce the
temperature of storage rooms.

Of the uses and benefits of cold storage it can be truthfully stated,
that nothing in recent years has been of more direct benefit to the
farmer, stock-raiser, and fruit-grower. But a brief period has passed
since cellars, caves and underground grottos served as the best means,
and in a limited way under certain conditions of weather, for the
protection and preservation of perishable articles.

To-day machinery has made it possible to control temperature at any
degree and in all climates. The burning heat under the equator would not
be an impediment to secure a zero temperature in a cold-storage room.
