Colonel Philip A. Moore will give an illustrated talk on "The Trail Riders of the Rockies" at the Union tonight at 7 o'clock. The lecture will be based on his experiences gained in travelling over 25,000 miles of trail in the Rocky Mountains, where he has spent much of his life in various occupations, becoming successively prospector, guide, big game hunter, explorer, and anything that offered new experience or excitement.

When the rumor of the outbreak of the World War reached him, he was in the Canadian Rockies, so far removed from civilization that he was forced to walk two hundred miles to the nearest enlisting station in order to sign up. He was immediately sent to Flanders, where he served with great distinction, and received his commission as colonel. As soon as peace was declared he returned to his life in the west, which he has now abandoned for a time in order to take up the lecture platform. His services have proved invaluable to the Bureau of Commercial Economics of Washington, under whose auspices he will speak tonight.

Colonel Moore's lecture will be illustrated by hand-colored slides of the animals and scenery of the Rockies, and by moving pictures taken under his direction last summer.
