Prof. Felix , . Jtiwiowskl, says It Is ready I lor a heavy research program that E -----vVH will include Htudies on types of ittrpluneB nulically different from those now neon in tho nlr. . Tho controversy over the rein- 1 live efficiency of monoplnncs and multiplanes is far from ended, ac cording to Professor Pawlowskl j who believes that tho monoplane's ' present popularity !s a transitory j whim of designers. He nnd an iih- sociate, U. V. Kerber, plan further . research with multiplanes in the ! new Michigan wind tunnel. "The monoplane is well adtipted : to tho present stage of tiir trans portation," Professor Ptiwlowskl fays, "but when airplane designers j are called upon in future years to construct trans-oceanic planes big . enouph to carry hundreds of peo ple, the multiplanc uirplane with three, more wing surfaces appears to otter greater possibilities." Kerber already has carried on some experiments in (he Michigan wind tunnel during the last three years with a uuadrupltinc having four wings sets back In tiers above each other. The model, developed to perfect scale of a full-sized ma chine, proved to have high lift ef ficiency and other characteristics favorable to operation. Experts lu , the industry recog nize that the universities must be depended upon for development of i u.ure aeronautical engin e e r s. Kerodynamics and other special ized subjects in which the aero nautical engineer must have thor ough training probably can be taught with greatest ease and-efficiency through competent uni versity instruction. Wind tunnels, which are the laboratories for research in aero dynamics a highly technical field embracing the study of airplanes' flight properties have a romantic appeal to the popular imagination. They make It possible to study exactly how an airplane will act in winds of velocities up to several hundred mites ah hour, without ever building the full-sized air ..pliijic... Toy-like models, built with groat accuracy and precision, are used. Delicate wires suspend the models j in the tunnel air stream, and sen- j sitive instruments record the j forces acting upon the model n,x if it were in flight. Tho fnivi'rsity of MU-hignn wind tunnel. designed by Professor Pawlowskl, differs from most oth ers at university, military and eommercinl aeronautical Inborn- j torles. ' I It has a dun! return for the air blown through the main throat of the tunnel, so that the air circu lates constantly instead of being blown out one end. It also has a unique arrangement which makes , possible an adjustment of the tun nel's throat to diameters of ffvo, six, seven or eight feet. This makes possible flexibility In its use for research problems involving nil-streams of various velocities up to 250 miles an hour.

This startling increase in pro duction is based on the reports for the first 11 months of thn year and an estimate for I lecember. exact figures for which arc not yet available. Manufacturers forecast an .even larger increase in 1929 because of added road mileage contemplated nnd the Increasing demand for automobiles abroad. Tho production figures for each month in 192 follows: January. 31.78; February, 323,796; March 413.79; April. 41H.104; May, 425,783: Juno, 391,790; July, 3U2, 076; August. 46l.i9S; September. 415.2HG; October,. 397. 09; ftml November, SG0.O3O.. Tho figures for . December, still unavailable, are almost Certain to exceed the 1927 mark for the twelfth month of 133,57 1 automobiles, experts nay. Although many factories were preparing for production of hew models and slowed production of their 1928 designs, more motor vehicles, were shipped from fac tories In the. United States in No vember than in tho same month In 1927.. Report made to the department of comemrec show that 256, 32ft motor vehicles, of which 217.359 were passenger cars and 39,680 were trucks, were produced in November. These figtm-s compare favorably with 134.370 vehicles produced In the mi me month f 197. . " Approximately 4.300,000 auto mobile vere produced in lt28 while 3.401.J2G were shipped from Qthoir factories In 19:7. The 12$ production figure may pass the 4.4 00,000 mark "when all reports have been made. The advance showing of the new 1929 six-cylinder Chevrolet ears al the Pierce-Allen Motor Co. last week was largely attended and the new cars met with universal satis faction.

With all makes of cars on display with the improvement for 1929 a matter of record it must be plain to everyone that the new Buick with Masterpiece bodies by Fisher merits final recognition as the most advanced automobile of the day! . . , . . Its arresting new body lines and contours stamp it im mediately as the newest and most distinctive motor car atyle. Its new Valve-in-Head six-cylinder engine is not only the most powerful automobile engine of its size in the world but the leader in getaway, swiftness and stamina as well. Moreover, a host of new luxury factors make the new Buick the most comfortable automobile to ride in and to drive. Scores of thousands of buyers have recognized these facts and entered orders for the new Buick during the past five months. And scores of thousand of others are acclaiming Buicks advanced quality at automobile displays: throughout the country. . . . : Every comparison proves the new Buick an outstanding value as new and unrivaled today as the day it appeared! .
