NEW NAVAL PROGRAM PLANS BATTLEBOATS
 OF IMMENSE SIZE
Each of the Super Battle Cruisers Will Be Twice as Long as Any Ship Which Participated in the Spanish War.

WASlNGTON Nov 27.-Some idea of the size and power of the super. battlecruisers proposed as part of the new naval program may be gained from the fact that each one would be 500 feet long-more than twice as long as any battleship which partic- ipated in the Spanish-American war more than 200 feet longer than any nattleship now afloat and ten feet longer than was the Lusitania
 Tests for hull models for the giant cruisers are proceedings at the model basin m the Washington navy ward 10 determine just how much borse. power will be required to drive fban 50 knots an hour. the speed fixed bv lhe navy general board.

 The navy model basin is now eauip- led with a waye-msking device which ests the rolling qualities of a shin lesisn and also her ability to sustain Ugh speed in rough water.

In slack periods a regular series of tests is produced and the results noted in order that the whole scientific field may be covered The officer in charge presents the new data gather ed before a scientific society each year and private designers can now work out the hull of a merchant ship on the formulas gathered by the gov. ernment About a fifth of the work now done in the basin is for private 5hipbulders who send plans of pro posed ships 10 the navy yard where models are constructed and tested The plant soon will have a capacity of producing and testing one model
