iinually pouring into the tank. There is
TO necessity To seek either spot at present TO
escape the heat The ravine, ho Eever is
Just as beautiful as ever, the touches OF frost
having scared the foliage into golden and
russell huts, and the exhibits I'm the annex
are just as wonderful rs ever. The pieces of
mechanism around the borders of this tsnk
are curious In some Instances aud are for
purposes not generally understood.
Those who have meandsred along the
LoIthern edge OF the tank, watching the
great streams OF water pouring from the
pipes overhead. have found themselves sud
