There is a great deal in ventilation. Three-fourths of the trouble which we now have from scalding would be obviated if air-giving were properly understood. The first principle to be learned is this: Ventilate to keep down the temperature, not to bring it down after it has once been allowed to get very high. Ventilation should be practised very early in the morning. If the house is not looked at till 8 o'clock, it may happen that the temperature has risen so high that it is impossible to get it down. Rather than this should happen, leave a little air on all night. Late ventilation shows its evils the most strongly when a spell of dull weather is followed by a sudden outburst of sunshine. Owing to the surface of the berries being cold, moisture condenses on them, and when the sun bursts out this is lickcd up so rapidly that the skin suffers - hence "scalding." Scorching of the leaves may arise from the same cause. Look at it which way you will, the Grape grower should be an early riser. If there are ventilators on both sides of the house, do not open those on the windward side in cold weather. The syringe should be used freely about 3 p.m. and an hour afterwards the house should be shut up, in order to bottle up as much heat as possible.
