Mr. Evans was about to leave for a long business trip to the south of the province and we took possession of a pretty temple just within the north gate of the city. Here we read a great accumulation of mail and learned that a thousand pounds of supplies which we had ordered from Hongkong had just arrived.
Through the good offices of Mr. Howard Page, manager of the Standard Oil Company of Yün-nan Fu, their passage through Tonking had been facilitated, and he had dispatched the boxes by caravan to Ta-li Fu. Mr. Page rendered great assistance to the Expedition in numberless ways, and to him we owe our personal thanks as well as those of the American Museum of Natural History.
All the servants except our faithful Wu left at Ta-li Fu but, with the aid of Mr. Hanna, we obtained a much better personnel for the trip to the Burma frontier. The cook, who was one of Mr. Hanna's converts, was an especially fine fellow and proved to be as energetic and competent as the other had been lazy and helpless.
Our work in the north had brought us a collection of thirteen hundred mammals, as well as several hundred birds, much material for habitat groups, and a splendid series of photographic records in Paget color plates, black and white negatives, and motion picture film. But what was of first importance, we had covered an enormous extent of diverse country and learned much about the distribution of the fauna of northern Yün-nan. The thirteen hundred mammals of our collection were taken in a more or less continuous line across six tremendous mountain ranges, and furnish an illuminating cross section of the entire region from Ta-li Fu, north to Chung-tien, and west to the Mekong River.

It is apparent that in this part of the province, which is all within one "life zone" even the smallest mammals are widely spread and that the principal factor in determining distribution is the flora. Neither the highest mountain ridges nor such deep swift rivers as the Yangtze and the Mekong appear to act as effective barriers to migration, and as long as the vegetation remains constant, the fauna changes but little.
