Donald B. MacMillan, the famous Arctic explorer will deliver his lecture on "Five Years with the Polar Eskimos", which was postponed from January 7, next Tuesday evening at 8 o'clock in the Living Room of the Union. His talk will be illustrated with 140 photographic slides of his Arctic travels.

Mr. MacMillan was Peary's assistant in 1908 on his successful trip to the North Pole, and has a large store of experiences gained through that expedition and many of his own, from which to draw material for his lecture.

He was born in Provincetown in 1874 and was graduated from Bowdoin College in 1898. For ten years thereafter he taught in various New England preparatory schools, during which time he was an instructor at Worcester Academy, Swarthmore Preparatory School, and principal of Levi Hall High School of North Gorham, Me.

In 1908 he left the teaching profession and became assistant to Peary on his successful dash to the North Pole in 1908-1909. Throughout the subsequent three years, the explorer made cruising trips along the Labrador Coast, with the especial purpose of studying the Eskimos there. The Crocker Land Expedition, lasting from 1913 to 1917 was commanded by Mr. MacMillan, and the newest of his undertakings is the Bowdoin-Baffin Land Expedition, which is scheduled to take place in 1920-1921.

Throughout his Arctic wanderings, Mr. MacMillan has covered more than 10,000 miles by dog teams in company with the Polar Eskimos. He has made an extensive study of the Smith Sound Tribe and particularly of the bird and animal life of the farther North.

The lecture Tuesday night is open only to members of the Union, who will be admitted upon showing their membership cards.
