84 H. F. Reid-Studies of Muir Glacier. These suggestions are not, of course, intended for scientific explorers; but for persons of some scientific knowledge who may wish to add to the general pleasure of a stay at Muir glacier the special interest of a definite object, viz, to increase our knowledge of the region. I may say that a small piece of work done well, such as the mapping of a single tributary e. g., Dirt glacier, White glacier, or Granite canyon-is more useful than indefinite observations over a wider range.
