The above considerationshowever, are believed to indicate the essential and controlling factors for the stocky type of columnshere considered, and, in fact, should be taken into account to a large extent in columns of sleuderness ratioup to 1201/r. In the opinion of the writers this behavior is shown very clearly and in an exagger
