They were weighed at the beginning of the experiment and at intervals for four days. The following results show the loss in ounces from the original weight:. The total losses in water from the uncultivated, cultivated and sod boxes were respectively 10, 5 and 25 ounces, or in per cent of loss in relation to weight of soil 8, 4 and 21 per cent respectively.

They were weighed at the beginning of the experiment and at intervals for four days. The following results show the loss in ounces from the original weight:. The total losses in water from the uncultivated, cultivated and sod boxes were respectively 10, 5 and 25 ounces, or in per cent of loss in relation to weight of soil 8, 4 and 21 per cent respectively. The cultivated plot lost 2 ounces more than the uncultivated during the first five hours. This was due to the evaporation of moisture from the top layer forming the mulch. It lost no more during the next 24 hours and only one ounce in the next 3 days, compared with 6 from the uncultivated box and 17 from the sod plot. Now, these boxes held but 37 per cent of a cubic foot of soil. On the basis of these results an acre of soil would lose from its first foot of depth the following amount of water in 4 days: Uncultivated 36 7-10 tons Cultivated 18 4-10 tons In grass 91 8-10 tons \\'hen you that almost 85 per cent of each apple you see before you here consists of water you may gain a better appreciation of the extent to which sod or lack of tillage in an orchard robs the trees of the water necessary for the best devel- opment of their fruits. And no account is here taken of the immense amount of additional water that is daily needed by the trees themselves to perform their functions. I do not wish to leave with you the impression that all orchards must be tilled, for there are too many in the State of.
