the house. The sides are two feet
above the ground, and the entire structure is but ten feet in height,
enabling the gardener to reach nearly every part of the roof from the
ground. The posts may appear to be an objection, but in practice they
are found not to be so, but are useful to train the vines upon. Five
rows of vines are planted, two in the usual manner at the sides, and one
row along each line of posts. The object in planting thus, was to get
as much fruit as possible in the shortest space of time. These centre
vines will give several crops of good fruit before they will be much
interfered with by those trained upon the roof. 9x15 glass was used in
glazing, to lessen the expense of sash bars, the glass being laid the
15-inch way. This glass, being very true, has made a good roof, but
10x12 is as large a size as will usually be found to answer. This house
is distinguished from most of our other designs by the greater amount of
light admitted, owing to the absence of rafters and the less than usual
number of sash bars. The sides and ends are boarded perpendicularly, and
battened. Ventilators are provided on each side of the ridge and over
the doors, while the sashes hung in the doors furnish sufficient bottom
ventilation. It was desirable to have the house raised or appear higher
owing to the slight depression of the ground at the site, and for this
reason the border was all made above the surface two feet and a half in
height, composed largely of decayed sods, with an addition of muck, coal
and wood ashes and a small quantity of stable manure. It has been found
to work admirably, and preserve an even moisture throughout. Elevated
borders are highly recommended by some exotic grape growers, and our
experience with them is much in their favor. At present the inside
border is alone completed, as it was desirable to plant the vines, and
sufficient materials were not at hand to complete the whole. Vines were
planted the 1st of June, 1864.

DESIGN No. 8.

THE POLYPROSOPIC ROOF.

Polyprosopic is not a dictionary word, at least we cannot find it in our
two-volume large quarto edition of Webster, but Loudon makes use of it
to name a special form of roof sometimes made use of in the construction
of Horticultural buildings, the true meaning of which we believe is,
that the interior side or outline of the rafter is curvilinear and the
exterior formed of planes or faces.

A very extensive practice in the design and er
