Cous Herschel and of Ericsson. Pro-
fessor Langley, of the Smithsonian
Institution, has written powerful
words calling attention to the neces
sity for such an invention. He has
declared that the human race must
depend in the future upon the sun for
heat and power It is method for
tho utilization of this heat of the sun
in practical way that DR.. William
Calver claims TO have discovered In
substantiation Of his claim, he attains
results which would seemingly con.

seems thoroughly wrapped up in tho
work that he has accomplished and
the work that he has in view.
