The Modesto Bee is also on microfilm at the Merced County Library. (I live in Merced County.)
I am not trying per se to confirm that L.M. Boyd said there were vegetarian crocodiles. I am really trying to find either the source(s)for his statement or other independent, corroborated research that there are, indeed, several vegetarian crocodiles. (In other words, I know what he said, I just want real proof.)
Since "Louis Malcolm (Mal) Boyd, popularly known as L. M. Boyd," had a nationally sindicated column, that article was also carried by the San Francisco Chronicle/Examiner, and other large newspapers. If I recall correctly, his column was called by different names in different papers i.e. "The Grab Bag" or "The Answer Man" or just "L.M. Boyd".
