Hadj Cheriff was apparently an Egyptian; his name in Arabic means 'Prince who has made pilgrimage to Mecca'. He performed in 1890s U.S. vaudeville under several variations of that name, including 'Hadji'. Apparently he did a bit of everything, but wasn't particularly adept at anything.
A previous IMDb reviewer, Snow Leopard of Ohio, says that this film depicts Cheriff performing 'cartwheels'. That's not correct. What we see here is the acrobatic manoeuvre known (in the USA and elsewhere) as a forward tinsica. Sort of a cartwheel with a half-twist, basically a tinsica (also spelt 'tinsika') is performed so that the hands touch the ground with one arm in front of the other (as in a walkover) but with the feet landing side-by-side, as in a handspring.
I don't blame Snow Leopard for the error. Tinsicas were once a standard part of gymnastics training in the USA, but for some reason are no longer taught to Stateside gymnasts. When I watch U.S. gymnastic competitions (which I do far more often than you might suppose), I see nary a tinsica.
This short film consists solely of a stocky bearded man performing forward tinsicas, over and over. The film has some slight merit if someone needs to know what a tinsica looks like. But Hadj Cheriff's tinsicas are not impressive: they have very little amplitude, and he consistently leads with his right arm while going too far sideways, as if doing a cartwheel. A more adept gymnast would alternate leading arms, performing the forward tinsica *forward* rather than sidelong. I would be more impressed if Cheriff could do a backward tinsica, which is more difficult. Evidently he couldn't, or he would have performed a few in this brief film.
For its historic significance and for demonstrating what a (very badly done) tinsica looks like, I'll rate this movie 3 out of 10.
