A Lumbermen's Camp Which Can Be Moved from Place to Place on Rails
IN his account of the life of the rough and ready northern woodsman, Rex Beach often painted a realistic picture of his poorly-constructed and unsanitary home. As a rule, lumber camps enjoy but a tem- porary existence, and for this reason the houses are ramshackle affairs. The logging crew live in them a few weeks and then move on to another camp. The old camp is left at the mercy of the elements and no attempt is made to repair it, unless the loggers happen that way again.
I n Ever e 1 1 , Washington, the temporary camp has been replaced by a permanent mobile camp con- sisting of railroad coaches. The coaches include kitchen, dining and bunk rooms for the men, blacksmith shop, engineers' and administrative offi- ces, as well as equipment for heat- ing, lighting and

��Pointers for the Inventors Working on the Submarine Problem
THE Naval Consulting Board has re- ceived literally thousands of sugges- tions and plans for destroying submarines and protecting merchant ships against torpedo attack. In addition, the Secretary of the Navy has also heard from inventors on the subject. The Naval Consulting Board has considered these plans and apparently has come to the conclusion that most if not all of them are worthless. In Bulletin No. I which was published recently by the Sec- retary of the Con- sulting Board, No. 13 Park Row, New York city, and which bears the title "The Submarine and Kin- dred Problems," the difficulties that must be considered by the inventor are in- structively summar- ized. That Bulletin ought to be in the hands of every man who thinks that he has solved the sub- marine problem. It disposes of the electromagnetic devices suggested for detecting and destroying submarines; it dismisses the idea of "charging the sea with electricity"; considers the best and worst methods of protecting a ship against submarine attack ; dwells upon the airplane as a device for discovering the sub- marine ; comments on underwater sound-re- cording de- vice, work- ing on the microphone principle ; brushes aside the use of nets or screens as a protection for cargo- carrying ships, and points out the merits and defects of present methods of destruction.
