WON'T DENT WON'T RUST 

 AIR-TIGHT 



Witt's Can and Pail are made of heavy, deeply 

 corrugated steel — galvanized and rust-proof — 29 times 

 stronger than plain steel. Witt's resists the hardest 

 knocks. It outlasts two ordinary cans. The lid fits 

 air-tight and stays tight, but 

 it can't stick. Buy Witt's 

 for your home. It saves you 

 money. Write for booklet and 

 name of nearest Witt dealer.

The Grip of the Ice Fields 



Great indeed is the fascination which the Far North has for certain daring:, 

 adventurous men. Donald MacMillan was at the Pole with Peary. When 

 Peary's ship, the "Roosevelt," was on her way back, MacMillan hoped 

 the ship would get stuck so they would be held there for at least another 

 year. But the Pole had been found. What else was there to do? 



There is a place in the North— the largest unexplored white spot on the 

 surface of the globe — a place nobody was sure of. And this was the goal 

 that Donald MacMillan set out to reach. 



His expedition was organized by the American Geographical Society and 

 the Museum of Natural History. They expected to be away two years; in- 

 «tead they spent four years of terrible hardship, of hair-raising adventure, 

 of long, patient waiting; but they found what they set out to find, and 

 MacMillan has told the story in a most remarkable book.
