or multiplication ot such a unit for smaller or larger requirements 
obviously depends upon conditions which can not be considered here 
in detail. Under conditions where such a shed, even on a smaller 
scale, would be too large and permanent the necessary protection can 
be provided to the individual stacks of lumber by piling the timber 
on the proper foundations and then virtually building a shed over 
and around each pile. In such cases the roof may be of thatch or 
rough boards laid in such a fashion as to keep off the sun and pitched 
and overlapped so as to shed the rain. The ends and sides of the 
piles should be protected by tacking up rough boards or the equivalent 
of tight lattice work to keep off the sun and wind. The side protection 
may be removed gradually piece by piece as the condition of the 
lumber requires. 
(c) Requirements of various species. — In large timber yards it is 
not necessary to provide seasoning sheds for all species, but the more 
refractor}" woods must be seasoned in sheds in any case. 
Of the species dealt with in this investigation the following are 
very refractory and liable to severe depreciation from surface crack- 
ing, splitting, and warping, and must be given ample protection against 
too rapid drying. 
Aegle Marmelos. 
Anogcissus acuminata. 
Anogeissus latifolia. 
Anogeissus pendula. 
Careya arborca.
