Ben,
there is no index to the authors for all the many YSA volumes. I've read them all, but it's just to much to remember everything. So what you are asking is, me flapping to all the pages
I can do that for you, but it will need some time - okay?
But, an other thing I did right now! I looked into my copy of
Lake & Wright for all listed Art Youngs publications. You asked about Lions and Bear stories - here is what I have found:
Young,A. (1926): African lions and the longbow. -
Field & Stream, July 1926, 11-13, 86-7
Field & Stream, Aug. 1926, 24-6
Field & Stream, Sept. 1926, 22-3, 98-100
Young,A. (1926): Loaded for bear - Big game hunting with the bow and arrow. -
Collier's, 78, 11 Sept. 1926, 32, 39.

BTW: have you read
WHITE, Stewart Edward (1926): Lions in the Path. – 292 p., 35 figs.; Garden City, New York (Doubleday, Page & Co.).
It covers the 1925 Pope & Young African adventure from the PH's point of view. There are reprints available, for example this one:
WHITE, S.E. (1987): Lions in the Path. – 292 p., 35 figs.; Prescott, Arizona (Wolfe Publishing Co.).
Ben, how does this Monday feel? There are still some minutes of yesterday left in my place ...
