Eskimo Note June 7 Point Barrow, Alaska so that his boats had to push through their accumulated bodies for several miles before reaching open water. The lemming cycle runs in about a 3 to 4 year cycle. That is there is a buildup of the population for 2 or 3 years, so that in the final winter they increase tremendously and eat themselves out of house and home. Then comes the big die off, aided by the various predators, the weather, and lack of food. The few that survive exist until the food supply is replenished in a season or two, and then once more there is a flurry of reproduction until the food supply is again out run. There is a nice adjustment by the climate and plants to this situation, for the plants are perennials with their roots set solidly in ground that is frozen through the winter and unavailable to the rodents that might attempt to dig them. With the reserve of ready roots the grasses are able in a season to recover and provide a fountain of forage for the lemmings. The mice, however, take a little longer to make a show because really very few are said to survive the trial that is at this moment upon the popu- lations. The next few days and weeks should be of great interest in this regard.
