EDDIES.

   It is quite surprising what a number of new interesting machines have made their debut in the U.S.A. during the last year or so, and in reviewing the ever-growing list of newcomers one cannot help noticing how the general trend of design seems to be in the direction of the fast tractor biplane. Sorting out mentally those that come to mind, a goodly number of the more recent ones are clearly influenced by German practice as regards their general lay-out. Several of them have the arrow type or back-swept wings, to which class belongs also the little biplane illustrated in the accompanying photograph. This machine was designed by Mr. Frank Pontkowsky and built by the Schaap-Sestak Aviation Co. of Chicago. It is fitted with a 50 h.p. Gnome engine, and is said to be a very fast and steady little machine to handle. Among the pilots who have flown it is, I believe, Earl S. Daugherty, who claims to have flown more different types of machines than any other American aviator.
