There are many who believe that the
naval battle at Santiago proved that har-
veyized armor Is sufficient protection
against projoctiles as manufactured today.
Whether this be true 1t Is evidont that

the weight of the armor can be greatly
lessened, and at the same time furnish
protection equal to that of the harveyized
armor.
The introduction of kruppized armor
