As this bird was marked July 3, 191G, and was found October 22, 1922, on the shores of Tulare Lake, a south- west migration movomont from the Salt ages of birds and so forth to be solved by bird banding, such as differences in plum- age at various ages and at various seasons ; whether the birds return to the same nesting sites; rate of growth ; and diseases affecting different species as dis- covered by those cooperating in this work under the Biological Survey. As the practice becomes extended it is anticipated that much valuable data concerning west- ern birds will be collected in this way, as has alri'adv hotni dom^ in the Fig. 30.

The nests of snowy heron are found in colonies in the lower Bear River marshes where, on July 3 and 14, 191G, 83 nestlings were banded. Three of the four recovered were found in Mexico, the fourth in Arizona, upon dates that would indicate that these herons from the breeding grounds of Utah win- ter on the west coast of Mexico. There are many other problems aside from migration routes, length of flights. SCIENTIFIC WORK OF THE COMMIS- SION APPRECIATED. That the valuable studies of California fishes prosecuted under the administration of Mr. N. B. Scofield, in charge of the Commercial Fisheries Department, are of the very highest order and an accomplish- ment which promises soon to place Cali- fornia ahead
