Natural water loss in selected drainage basins

Determinations of areal rainfall, run-off, and water loss, comprising largely evaporation from land surfaces and transpiration by vegetation, are essential in indicating the hydrologic characteristics of river basins. This report is primarily a statistical study that presents the results of computations of annual water loss, or annual rainfall minus annual run-off, for river basins in the humi

Neascus infection of black-head, blunt-nosed, and other forage minnows

Black‐head, blunt‐nosed, and other minnows were found infested with encysted flatworms in ponds at Leetown, West Virginia. The mortality in a 2.2‐acre pond stocked with 100,000 black‐head minnows was about 250 per day during four weeks of observation. Heavy infestations caused sterility in the minnows. The cyst and parasite are described briefly and the probable life cycle given, followed by certa

A small urn‐shaped peritrichous protozoan, apparently an undescribed species, was found on the gills and bodies of largemouth and smallmouth black bass in ponds at Leetown, West Virginia. A heavy mortality among a lot of fingerling largemouth bass probably resulted from suffocation due to the organisms on the gills. Specimens of the parasite, preserved in formalin, measured about 57 microns in len
