FOR THE GUMS 30c and 60c tubes All Druggists FORHAN CO. 214.6th Avenue, N. . The Largest Unexplored White Spot in the World Far off in the Northwest lay the largest unexplored white spot on the surface of the globe-one-half a million square miles. That was the goal for which Donald MacMillan set out in the year 1913 He knew that before him and his companions lay "two years of uncer tainty, of adventure, of wonderful and strange sights, of extreme Happiness and abject misery," and the two years stretched to four. But the goal was reached; the work was done. The story of those four years is told in his new book FOUR YEARS IN THE WHITE NORTH By Donald B. MacMillqn MacMillan was with Peary when he found the Pole. The MacMillan Expedition was known as the Crocker Land Expedition, and was sent under the auspices of the Museum of Natural History and the American Geo graphical Society. It explored the unknown land-found records of Peary and other great explorers-and much other material here published for the first time. This is truly an epoch-making book.

This is usually the first stage of Pyorrhea-an insidious disease of the gums that destroys the teeth and un dermines bodily health. Gradually the gums become spongy. They inflame, then shrink, thus exposing the un enameled tooth-base to the ravages of decay. Tiny open ings in the gums form gateways for disease germs to enter the system. Medical science has traced many ills to these infect ing germs in the gums weak ened by Pyorrhea. They are now known to be a frequent cause of indigestion, anaemia, rheumatism, and other serious conditions. So watch carefully for that first tenderness or bleeding of the gums. Try Forhan's im ,mediately. It positively pre vents Pyorrhea (Riggs' Disease) if used in time and used con sistently. And in preventing Pyor rhea it guards against other ills. Forhan's (For the Gums) cleans teeth scientifically as well. Brush your teeth with it. It keeps the teeth white and free from tartar. If gum-shrinkage has al ready set in, start using For han's and consult a dentist immediately for special treat ment.
