^ And speaking of submarine boats the model on exhibition in the window of J. N. Martinek's jewelry store is worthy of more than passing comment. Mr. Martinek, its inventor, is also making an effort to place his machine at the service of the government but as yet he has not been able to get the at’ tention of the Navy Department.

Mr. Martinek says that his boat is entirely different from the seventeen boats upon which patents have so far beengranted._ ^
