side of the house, at _d_, _d_. There are two other
rows at _e_, _e_. There are also a few vines at _c_, and at the ends of
the house. The rows at _d_, _d_, form fruiting canes half way up the
rafters; those at _e_, _e_, go to the roof with a naked trunk, and
furnish fruiting canes for the other half of the rafters. The fruiting
canes are thus very short, and easily managed. The house was planted in
the month of April, with such grapes as Black Hamburgh, Victoria
Hamburgh, Wilmot's Hamburgh, Golden Hamburgh, Muscat Hamburgh, Chasselas
Fontainebleau, Frontignans, Muscat of Alexandria, Syrian, Esperione,
Tokay, and some others. The plants were very small, and the wire worm
injured some of them so as to make it necessary to replant; but the
growth of those not injured was very good. A fine crop of Melons,
Tomatoes, Strawberries, etc., was taken from the house the first year.
The second year a few bunches of grapes were gathered, and every thing
went on finely.

This is the third year in which the house has been in operation. Our
last visit was in the early part of August, 1863, when we counted 734
bunches of grapes, weighing from one to seven pounds each, the Syrian
being the grape which reached the last figure. Almost as many bunches
were thinned out. In some cases too many are left, but they look very
fine. The Muscats are extremely well set, and some of the bunches will
weigh fully three pounds. The Black Hamburghs look quite as well; but
the finest show of fruit is on the Esperione. The large number of
bunches is owing to the manner of planting; so many could hardly be
taken the third season from a house planted in the ordinary way. The
canes, it will be borne in mind, are now only fruited about half their
length.

The exposure of this house is a very bleak one, and the climate cold
and fickle. In order to provide against a late spring frost, a coil of
one inch pipe was inclosed in brick work, with a fire chamber under it.
From this coil a single one inch pipe was carried around the house next
the side sashes. It is found to answer the purpose, having on one
occasion kept the frost out of the house, when the crop in the house of
a neighbor was destroyed. In many places, some resource of this kind is
necessary, and a small boiler with a single pipe will in most cases
prove sufficient.
