Here is a nice lot of Coker’s pedigreed tobacco seed which have 
been sifted once and cleaned twice on air cleaner. 
2. When the seed pods are all mature, the heads are gathered 
by hand, threshed on a small threshing machine and seed spread 
out to dry. This drying process usually requires about ten days. 
3. The dried seed are sifted by hand to remove the larger 
trash and are then put through an air blast cleaner to remove 
smaller trash, dust and light, immature seed. 
4. The next step is treating the seed with a solution of formal- 
dehyde and water, soaking them from eight to ten minutes, 
then washing thoroughly in open, cloth covered vats with large 
quantities of water. Great care must be taken in preparing the 
solution, in timing the treatment and in washing in order to 
avoid damage to the seed. 
5. The treated seed are then spread in a thin layer on racks 
to dry, which usually requires about two weeks. 
6. When the seed are thoroughly dry, they are sifted by hand 
and again run through the air blast cleaner. This process is 
repeated until only the large, plump, healthy seed remain and 
all foreign matter and trash removed.

containers, which are labeled with the name of the variety and
