his book on ice formation, and three

intensive study of icebergs was begun
in 1910. and in this year Dr. Barnes
j discovered the heating effect which
1 icebergs have on the surrounding
water, and invented his well known
microthennometer ice preventive
methods. His interest in ice jams led
him. in 1924 to evolve the theory of
their destruction by thermit, and he
put it to the test in February. 1925. on
the Waddington jam, claiming that as
a result of his work he freed a quar
ter of a million tons of Ice. A few'
weeks later he operated on the t'hiin
ney Island jam., near Ogdensburg. and
i it was estimated that nearly a million
i tons of ice were liberated by his meth
