sed with four
doors similar to double stable doors, and in the exact center of this
door space nail a 1x2 inch piece up and down to nail tray rest to. This
will give two rows of trays.

Put comb roof on with the flooring, leaving a vent open at comb two
inches the entire length of box. Make a V trough, which turn upside down
with one inch blocks under the corners; this gives ventilation and also
keeps out the rain; also make two six-inch holes below, to be opened or
closed as needed; this admits cold air and drives the hot air up,
causing complete draft. When the evaporator is full of fruit, the holes
below should be open full size, except at night, when fruit is nearly
dried, they should be closed, or partly so, which is done by tacking a
small piece of board over hole, which can be pushed to one side and a
nail or screw hold it in place. For the trays to rest on, take a piece
1x4, 37-1/2 inches long, nail a two-inch piece of same length in center
of this, on top; this gives one inch on each side for rabbet; this is
for center, and the rabbet rest is nailed to it through the 1x2 inch in
front, and through the siding on rear side. For the outside rabbet, one
piece 1x1 inch, 37-1/2 long; this nailed to the end of the box forms
rabbet for the trays to rest on. As many of these tray rests can be made
as needed to fill the box to near the top of doors. Place the first ones
twelve inches from bottom of box, and continue up, placing them three
and one-half inches apart. The trays are made of 1x1 inch strips for the
frame part, and are 2x3 feet square; bottom is made of plastering lath
sawed in two, and also cut in two lengthwise, as they are too wide; nail
these to bottom of frame, three-sixteenths of an inch apart. When used
for berries or sweet corn, tack cheese cloth stretched tightly over the
lath. There should be four doors, in order to have as small a space open
as possible in attending to the fruit; these are hung by light hinges to
outside and fastened by a wooden button screwed to center upright. The
lumber can all be bought at planer ready for use cheaper than it can be
cut by hand.

For the furnace, build a box of brick or stone as large on the inside as
the house, letting the most of the wall extend on the outside, in order
to have all the space possible inside, for heating. Build into this wall
at the bottom and ends a piece of heavy stack or sheet iron; any old
smoke-stack will do, but must be at least one foot
