The cause of this affection is the insufficiency of lime salts in the food, also to feeding hay of low, damp pastures, kitchen slops, and potatoes, or to Overstocking lands.
"Special Report on Diseases of Cattle"
U.S. Department of Agriculture J.R. Mohler
The bunch-grass which the cattle lived on, and which only Overstocking injured, gave way before the sheep; for these eat out the hearts of the young grass, and their range grew wider as the feed became more sparse.
"Two Years in Oregon"
Wallis Nash
Famine times account for some of the murders, and Overstocking I should say; it's done everywhere, in trout ponds, deer forests, and sheep runs.
