There is little text worth note in this paper, although there are some sketches and photographs (some aerial) that some might find of interest.

I attained my.pdf copy of this paper from Archive.org. The photographs in both versions (copies) that were available on that site were not particularly clear, although this might be a function of the computer I am using.

A better early document would be :
