make insulation doubly sure.

To provide for proper ventilation construct an intake for cold air at
the bottom, and an outlet for warm air at the top of the room. These
should serve all parts of the room, one being necessary for this
purpose every twelve to sixteen feet. Do not depend too much on
windows. Warm-air flues should be twelve inches square and six to
twelve feet long.

The attention to such a house is most important. Keep it closed
tightly early in the fall with blinded windows. When nights get cool
open the doors and windows to let in cold air, closing them again
during the day. On hot days close the ventilators also. In this way a
temperature of 36 to 40 degrees Fahr. can be secured in early fall and
one of 32 to 33 degrees Fahr. later. This is probably the cheapest as
well as the most practical method of farm storage.

Ice storage is quite practical in the North, but more expensive. The
principle of such a storage is to keep ice above the fruit, allowing
the cold air to flow down the sides of the room. A shaft in the middle
of the room will serve to remove the warm air. This method is open to
the objection of difficulty in storing the ice above the fruit.
Moreover the uniformity of its cold air supply is questionable.
Mechanical storage in which cold temperatures are secured by the
compression or absorption of gases is altogether impracticable for
individual growers, as it costs from $1.50 to $2.00 a barrel of
capacity to construct such a storage. Rents of this kind of storage
range from 10 to 25 cents a barrel per month, or 25 to 50 cents a
barrel for the season of from four to six months.

CHAPTER X

MARKETS AND MARKETING

Having produced a good product, there remains the problem of making a
profitable and satisfactory disposition of it. In many ways marketing
is the measure of successful fruit growing. Of what use is it to prune
well, cultivate well, spray thoroughly, or even pack well the finest
kind of product, if after the expense of these operations is paid and
the railroad and commission agents have had their share, no profit
remains to the producer? Many growers find it easier to produce good
fruit than to market it at a good price, and this is especially true
of the general farmer. Failure to market well spells failure in the
business of fruit growing. Successful marketing presupposes a
knowledge of the requirements of different markets as to quality,
varieties, and supply demande
