At this height they flourish without care, though the snow every winter is deep.

Even higher than this several bee-trees have been cut which contained over 200 pounds of honey.
The destructive action of sheep has not been so general on the mountain pastures as on those of the great plain, but in many places it has been more complete, owing to the more friable character of the soil, and its sloping position.

The slant digging and down-raking action of hoofs on the steeper slopes of moraines has uprooted and buried many of the tender plants from year to year, without allowing them time to mature their seeds.

The shrubs, too, are badly bitten, especially the various species of ceanothus.

Fortunately, neither sheep nor cattle care to feed on the manzanita, spiraea, or adenostoma; and these fine honey-bushes are too stiff and tall, or grow in places too rough and inaccessible, to be trodden under foot.
