106 THE CULTURE OF THE GRAPE. 



however severe this may be. The only effect from it, wliich 

 I have been able to discover, is a tendency to retard the push- 

 ing of the buds, and, on long canes or spurs, the causing of 

 the last eye to be blind. It cannot be of any advantage to 

 the vine, that is certain, and it should be guarded against by 

 early pruning. 



In the Gardeners' Chronicle for 1846, page 771, there is 

 an account of vines which had been winter-forced, and which 

 had ripened a crop of fruit ; as it was intended to remove the 

 vines, the causing them to bear a second crop was attempted ; 

 to effect this, the vines were severely pruned the first of May ; 

 they bled excessively ; notwithstanding this, the buds broke 

 well, and ripened the fruit in October. The wood, also, was 

 well ripened, round, and firm, with full eyes, and, so well did 

 it appear, that the idea of throwing away the yines was aban- 

 doned. They had previously been troublesome from overlux- 

 uriance. 



In ten days more, raise the temperature to 50° or 55° at 

 night, and by day, when cloudy, to 65°, or, when the sun 

 shines, to 75°. This temperature should be gradually raised 

 at night until the grapes are in bloom, when the heat should 

 be as equal as possible, 70° at night, 75° or 80° by day, 

 when the sun shines. Do not let the temperature of the 

 house, by artificial means, rise above 70° in this stage of 

 forcing. 



In May and Jime, we often have some very hot days, with 

 a bright sun and dry air, the temperature in the open air 80° 

 or 90°, and even higher ; in such weather, you cannot pre- 

 vent the heat of the house rising to over 100° ; if the air 

 should be very dry, it would burn the leaves, and injure them 

 more to have aU the lights and doors thrown wide open, than 

 a greater degree of heat with proportionate moisture would 

 do. 



The shrivel in grapes is caused, frequently, by too large a 

 crop ; sometimes by too much moisture at the roots, and often 

 by a sudden change of air, or too low a temperature ; the
