Most of the picking of hops on the
Pacific slope is done by Indians who

The mass of salt in it is estimated to be

found to work admirably in tests with

paid to developing and perfecting this
compound, and it is confidently asserted
that it will be equally available for

"A man lives in Turkalin, in the
province of Livonia, who can cure the
worst cases of hydrophobia. His medi-
cine for the disease consists of bugs of
the size of a FREELY, which he gathers
in the month of May in sandy places.
He keeps them in clean bottles until
they become perfectly dry and shriv-
elled to the size of the small COM
mon fly. Only one desc of two such
bugs kneaded in bread is sufficient to
cure the worst case of hydrophobia.
When the patient takes the dose his
temperature begins to rise. In about
three hours he has fit of raving mad
ness after which he falls asleep. When
he awakes the disease is gone.
