Case 9. Silver King's Memory of His Capture. At this moment we have a huge polar bear who refuses to forget that he was captured in the water, in Kane Basin, and who now avoids the water in his swimming pool, almost as much as any burned child dreads fire. Throughout the hottest months of midsummer old Silver King lies on the rock floor of his huge and handsome den, grouching and grumbling, and not more than once a week enjoying a swim in his spacious pool. No other polar bear of ours ever manifested such an aversion for water. The other polar bears who have occupied that same den loved that pool beyond compare, and used to play in its waters for hours at a time. Evidently the chase of Silver King through green arctic water and over ice floes, mile after mile, his final lassoing, and the drag behind a motor boat to the ship were, to old Silver King, a terrible tragedy. Now he regards all deep water as a trap to catch bears, but, strange to relate, the winter's snow and ice seem to renew his interest in his swimming pool. Occasionally he is seen at play in the icy water, and toying with pieces of ice. Memory in Bears. I think that ordinarily bear memory for human faces and voices is not long. Once I saw Mr. William Lyman Underwood test the memory of a black bear that for eighteen months had been his household pet and daily companion. After a separation of a year, which the bear spent in a public park near Boston, Mr. Underwood approached, alone, close up to the bars of his cage. He spoke to him in the old way, and called him by his old name, but the bear gave absolutely no sign of recognition or remembrance. How a Wild Grizzly Bear Caches Food. The silver-tip grizzly bear of the Rocky Mountains has a mental trait and a corresponding habit which seems to be unique in bear character. It is the habit of burying food for future use. Once I had a rare opportunity to observe this habit. It was in the Canadian Rockies of British Columbia, in the month of September(1905), while bears were very activism. John M. Phillips and I shot two large white goats, one of which rolled down a steep declivity and out upon the slide- rock, where it was skinned. The flensed body of the other was rolled over the edge of a cliff, and fell on a brushy soil-covered spot about on the same level as the remains of goat No. 1. The fresh goat remains were promptly discovered by a lusty young grizzly, which ate to satiety from Goat No. 1. With the remains of. Goat No. 2 the grizzly industriously proceeded to establish a cache of meat for future use.
