THE Use OF TRIPLE SCREWS
An extended use of quadrupe expansion and four
cylinder triple expansion engines abroad is noted
The question Of triple screws continues TO be agl-
-a+ed and though the great weight Of naval oPln-
ION seems 70 be against their use the principle IS
gaining advocates. particularly in France wheTe

The engineer officers Of all navies, it is stated,
arc watching with keen interest for a decision by
