There are few if any lumber yards in India at present of such a 
size that some form of seasoning shed over the whole is unnecessary 
or impracticable. 
(ii) The treatment of non-refractory woods. 
The essentials of the seasoning practice for soft, non-refractory 
woods and those which are especially liable to damage by staining, 
decay, and mould, particularly in the moist regions, are almost tlie 
reverse of those described for refractory woods. The first essential 
is to accomplish rapid, rather than slow, drying by giving the timber 
adequate protection from the rains, but allowing a free circulation of 
air through the piles. Such conditions are ordinarily much easier to 
bring about than those for woods inclined toward surface cracking 
and splitting. The timber should be piled under the protection of a 
good roof with the piles so placed in relation to each other that all 
parts are exposed to the air currents. The adaptation of such a simple 
shed to small or large requirements is simple. For large lumber 
yards, where cover over the whole is impracticable, the individual 
piles must be covered. In such cases the drive-ways through the 
yard should be placed parallel to the direction of the prevailing 
winds so that the piles themselves will stand with their length per- 
pendicular to the winds. The crossers between each layer will then
