NEW YORK Lf*\ The most spectacular decade in the whole history of sport, especially as its ! various and frenzied forma are practiced in the Untied States, has been brought to a climax with the close of 1930, a year marked by I an unparalleled assortment of!f achievements,\ The pinch of business depression may have been felt here and there i in the region of the box offices, but not to any conspicuous extent as the year winds up the dash along the *dlaziest athletic trail of allI time.Since the postwar boom era in sport began bigger spectacles, larger “gates and better extrava-f ganzas have 'been listed than those featuring the campaign of 1930, but in no other span of twelve months have such sensational accomplishments, record breaking I stunts or bewildering turns marked the competitive whirl.It is, indeed, the turn of an era, if not the close of an epoch, to find Bobby Jones in retirement after storming the supposedly impregnable quadrilateral of golf in perhaps the greatest individual sporting achievement of all time; to find Big Bill Tilden bowing, at last, to the challenge of American youth in tennis after a decade's j reign; to list the dethroning of, Babe Ruth as baseball’s home run j king, and the unconditional release, by minors as well as ma-j jors, of the one time king of pitchers. Grover Cleveland Alexander.It Is around these stalwarts that the great drama of American sport has been enacted. They have been among the invincibles of the decade that already has witnessed the passing of Dempsey. Leonard. Tun- j ney, Cobb, Speaker, Miiburn,I Johnston. They have 'been the', great drawing cards, the heroes of the country's youth.Tho it is the habit of the mob to look for the “kill, so far as \ champions are concerned, it may be a long time before any group i of pace setters turns up to compare with these. So far as a sue-} cessor to the one and only Bob ; Jones is concerned, the quest is likely to last indefinitely.
