To quickly assess the difficulty of the text, read a short excerpt:
dying or dead trees is about three hundred and fort}^ days. The period of activity — the feeding, growing, and maturing stages — of all broods of a single generation during the fust summer is about ninety days — July 15 to October 15 — and about one hundred and fifty days from the time activity begins the following spring — early in May — until the last individual has developed and emerged — early in October. Thus there is a total active period of about two hundred and forty days. The period of... inactivity — from about October 15 to early in May — is about one hundred and ninety-five days, making the total period of infestation of all broods of a single generation about four hundred and thirty-five days. This, of course, provides for an overlapping of the last broods of one generation and the first broods of the next, during July, August, and September.
NATURAL AND ARTIFICIAL INFLUENCES.
DROUGHT AND COLD.
It has been a common belief that the dying of the timber is caused by drought, but it is now clearly demonstrated that wherever the Black Hills beetle is abundant it kills the healthiest trees under all conditions of dry and wet seasons, moist or dry soils, north or south slopes, ridges, etc.
