ESTABLISHING FORESTS BY DIRECT SEEDING 215 



species can be sown separately or the seeds may be mixed before 

 sowing. Mixing the seeds of two or more species before sowing 

 should not be done if they vary in size or weight, because they 

 cannot be distributed evenly; it is best to sow them separately, 

 one crosswise of the other, provided the topography of the site 

 permits.

When hand sowing is undertaken in a rough country it is nec-

 guided by stakes set at suitable intervals, walks back and forth 

 across the area. The width of the strip that can be seeded by 

 each passage over the area depends upon the size and weight of 

 the seed. It varies with different species as follows:
