Here-worshippers, football fans, or anybody else interested in getting a free look at the Los Angeles Rams before they play the Boston Yanks on Sunday, need only walk to Soldiers Field any morning. The Rams have been working out there, starting at 9 o'clock, all week, with Messrs. Bob Waterfield, Tom Harmon et al on hand, Mrs. Waterfield, the hypermammiferous Jane Russell, may not be there--but there's always a chance.
