the fruit is nearly ripe the upper ventilators may be lef 
open at all times, but it is well to close the lower ones at 
night to keep out mice and currents of damp air.

the vines entirely exposed, as the rains would wash out 
many insects, and the birds assist in destroying the re

in artificial cleaning without injury to the vines,
