Weight and is $50 feet long. She is
N0peiled by two Mcintosh & Seymour
, ,sar cycle, marine oil engines, each of
lzV0 indicated horse power. These
d saglnes successfully burn the same
asayy grade Of fuel oil that is ordi-
4 afy burned under boilers. This
meets the objection of opponents of
ae motor ship that this type requires

asnhecott is ffty-fve barrels, driving

saols a,, This is equivalent to only ten
s. sslons Of oil required to drive the
