Hidden fire losses: Uncontrolled fires costly to soils, plant cover, water and timber supplies
by Woodbridge Metcalf
pp3-12, doi#10.3733/ca.v002n10p3
Abstract
Not available – first paragraph follows: Long time studies indicate that uncontrolled brush and forest fires profoundly affect soils, plant cover and water, as well as destroying man made structures and interfering with management plans for farms, forests and industries.

Hard seeds in beans: Proper temperature and humidity during storage important for germination
by James F. Harrington
pp4-12, doi#10.3733/ca.v002n10p4
Abstract

by H. T. Hartmann
