Field determination of nanogram quantities of mercury in soils and rocks
Margaret Hinkle, Kam Wo Leong, F. N. Ward
1965, Open-File Report 65-71
A method for determining nanogram quantities of mercury in geological materials is based on the catalytic effect of mercury on the reaction of ferrocyanide with nitrosobenzene to produce a violet-covered compound whose intensity if proportional to the mercury present. The mercury is released by heating a sample of soil or...

Herbert G. Hinson
1965, Circular 517
The magnitude and frequency of floods are defined regionally for small streams (drainage area, 1 to 150 sq mi) in North Carolina. Composite frequency curves for each of two regions relate the magnitude of the annual flood, in ratio to the mean annual flood, to recurrence intervals of 1.1 to...
