           Probably this table nee ds some explanation since some of the
spe- 
    cies not ordinarily thought of as being highly palatable shjow rather

    heavy use. Both Chrysothanmus and Sage occur only in very small quanti-

    tics. There nae probably not over one or two dozen sage bushes on the

    entire area. This scarcity is thought to be the exiclanation of their

    heavy use in this case, since observations throughout the winter indi-

    cate that isolatod individuals of a species are always browsed more 
    heavily than where they occur in some density. Apparently little balsam'-

    root was tcken after the first of Februar-y. Whether or not this condi-

    tion was general is not klnowiý,although it was observed that
large amounts 
    were being taken during January. The table also indicates a falling off

    in the amount of browse taken after the -idldle of March. This indication

    is somewhat verified by an exý,xaination of a paunch sample tnicen
within 
    the "Deer pasturo" on March 28. Crass constitutes the bulk
of the sam- 
    ple, although there is a small amount, probably 10 to 15 per cent of

    browse. Even this degree of use would mean extremely heavy use of low-

    lying browse range, because of the heavy concentration of deer on these

    areas during March and April. 
 
           Finally, if the estimates of density, etc. arte at all correct,

    the table indicates that 385 deer days use consumed apoproxi-mately 1.7

    forage acres of browse of a given comrposition. This disregards a num-

    ber of deer days th-Lat might be attributable to -rass utilization, how-
