showed that the outside range had about one-third more H. lioopesii 
plants than the area inside. This would indicate that at this time 
there was an actual reduction in the abundance of the H. lioopesii. 
July 25, 1918, the patch was visited and it was found that sheep 
had broken in on the upper part of the inclosure and had grazed it 
considerably, eating especially the dandelions. The H, Jioopesii of this 
season was very abundant and thrifty from the fact that the season 
was wet and favored the growth of the plant. It was very evident, 
however, that the H. lioopesii was much more abundant outside the 
inclosure than within. The area had been somewhat washed by the 
rains and the grass was not so abundant as would have been expected. 
September 9, 1918, a careful examination of the patch was made. 
By counting the plants on measured typical areas, it appeared that 
the H. lioopesii was nearly twice as abundant outside the inclosure 
as it was inside. The exact proportion was five to three. Inasmuch 
as the area outside had been badly trampled and many plants 
destroyed, it is probable that the difference between the two areas 
was really greater than that established by the count, for all the 
plants on a given area of the inclosure would be recognized, while 
many of those on the outside would have been destroyed by grazing 
animals. The difference in vegetation between the areas within and 
without the fence was very marked, and stockmen who had been 
observing the experiment considered it very good evidence of the 
beneficial effect produced upon the range by giving it an opportunity 
to recover. 
July 29, 1919, an examination showed that the H. lioopesii was 
still abundant, but, as in the preceding year, was in much smaller 
numbers than outside. 
August 5, 1919, a detailed examination was made. The H. lioopesii 
was matured and on account of the dry season was very nearly in 
the same condition that it was in September of the preceding year. 
Cattle had broken into the inclosure and had grazed upon the 
grass, apparently having, to a large extent, eaten the seed stems of 
the grasses. The grass was not quite so thick as early in the season, 
but this appearance may ha^e been due, in part at least, to the 
accidental grazing. Again a count was made of the relative number 
of the H. lioopesii plants inside and outside of the inclosure, and it 
was found that the average was in the ratio of llf to 19. 
During the summer of 1920 there was an abundance of rain in the 
mountains, with a consequent vigorous growth of all forms of vege- 
tation. When the patch was examined August 23 it was well covered, 
the wheat grass which grew all over it being especially marked. 
There was a considerable quantity of Gymnolomia multiflora, which 
being in blossom at the time, gave the patch a general yellow color 
when seen from a distance. The other plants present were dande-
