This report, like the one for the preceding winter, is a composite one. It includes the observations of a number of other field students besides myself. And I wish to acknowledge such assistance from Mr. A. J. Anderson, Mr. A. F. Allen, Mr. G. O. Ludcke, and Mrs. H. M. Bailey, all of whom have done more or less field work during the past winter season.
