What led to the growth of the sheep industry in Texas in the 1880s?

A new wool market was found among New England factories, increasing the breeding and export of Texan cattle.

Explanation:

George Wilkins Kendall, a pioneer sheep farmer near Boerne (Texas City now), widely promoted what he saw as ideal conditions for raising sheep in Texas.

With a strong emphasis on wool and not lamb, settlers in the West discovered that it was quite profitable to raise sheep because of the temperate and generally dry climate of the state of Texas.

The industry quickly spread across the Texas border.

At that time, the wool factories of New England had invented new techniques for manufacturing wool-based garments, so they decided to put a good price on Texan wool.
