20 THE GRAPE. 



should correspond with some peculiar style of architecture 

 in the dwelling-house, or other contiguous buildings (and 

 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 case may be conducted 

 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 scorching, 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 

 being more upright, 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 produce individually greater 

 crops. 



The frontispiece to this work is designed for the pur- 

 pose of showing a comple arrangement of the grapery to 

 suit all purposes, and at the same time to form a beautiful 

 architectural structure. Allowing the Cold Grapery to be 

 fifty feet long by twenty feet wide, and the others col- 

 lectively to be one hundred feet long by twenty-five feet
