maximum, and
at places distant from those areas where the influence might be expected
to be least.

The observation of rain-gauges and hygrometers at the same three
descriptions of locality.

In addition to the ordinary hours of observation, special readings of
the thermometers should be made as often as possible at a change of wind
and throughout the course of the short hot breezes alluded to already,
in order to admit of the recognition and extension of Herr Rivoli's
comparison.

Observation of the periods and forces of the land and sea breezes.

Gauging of the principal springs, both in the neighbourhood of the areas
of plantation and at places far removed from those areas.

1873.

DAVOS IN WINTER

A mountain valley has, at the best, a certain prison-like effect on the
imagination, but a mountain valley, an Alpine winter, and an invalid's
weakness make up among them a prison of the most effective kind. The
roads indeed are cleared, and at least one footpath dodging up the hill;
but to these the health-seeker is rigidly confined. There are for him no
cross-cuts over the field, no following of streams, no unguided rambles
in the wood. His walks are cut and dry. In five or six different
directions he can push as far, and no farther, than his strength
permits; never deviating from the line laid down for him and beholding
at each repetition the same field of wood and snow from the same corner
of the road. This, of itself, would
