SEED STORING. 
TMierever possible clean seed should be stored in air-tight recep- 
tacles of glass or metal. Seed retains its vitality imder any condi- 
tions of temperature and moisture much better in such receptacles 
than in any others, except when placed in cold storage, which is 
seldom available. Where neither of these methods of storage is 
available the seed should be thoroughly dried and stored in a dry 
and cool place. Some deterioration will take place under these con- 
ditions, but ordinarily not sufficient within one year to be of serious 
consequence. The storing of seed in cement cellars with the wings 
attached has been found by Austrian experimenters to give better 
results than storage with the wings removed. It is doubtful, how- 
ever, whether the slight saving in vitality offsets the advantage of 
handling and using clean seed. In every case the seed should be 
thoroughly protected from rodents, by the use of poison, by being 
stored in rodent-proof buildings, or by being hung in sacks out of 
reach.

Direct Seeding. 
Of the two methods of artificial reforestation, direct seeding and 
the planting of seedlings, the former where it can be practiced suc- 
cessfully offers the easiest and cheapest solution- of the reforestation 
problem. The seeding itself is a much simpler operation than phmt- 
ing. and with inexperienced labor, which is all that is generally ob- 
tainable, it can be carried on in conformity with the most approved
