should correspond with some peculiar style of architecture 
in the dwelling-house, or other contiguous buildings (ana 
these points ought often to be considered), the ridge-and 
furrow roof offers the greatest facilities, as it may be 
adapted to almost any form, without destroying its effi 
ciency, for the vines can be trained horizontally under the 
roof; the grapes also look very handsome in this position 
as they hang perpendicularly down from the whole sur- 
face above. The canes in this ease may be cunducted 
along the under surface of each furrow, and the side spurs 
fixed at right angles, which enables the operator to arrange 
the bunches with the nicest regularity. 
With respect to the inclination of the roof, it is desira- 
ble that it be not less than 45,° for the following reasons: 
our almost vertical sun at midsummer, when there is the 
greatest danger of seorching, will, at mid-day, strike the 
glass at an oblique angle, thus lessening its intensity and 
to a certain extent counteracting the evil The glass 
beng more upiight, the wind or draft admitted through 
the laps, will be somewhat intercepted, and confined more 
immediately to the inner surface of the roof, which will 
ensure a more equable temperature around the leaves and 
stems, preventing somewhat the tendency to mildew. A 
steep roof also gives an additional length of rafter on a 
given width of house, which is an advantage, as the vines 
with the general modes of training, have more extent to 
develop their energies, and preduce individually greater 
craps.
