Why it's an easy layup with a Mashie or a Spade Mashie. A Cleek is way too long a club, sir.

My guess is that this is some sort of caddie training, and the young boys are all learning the proper way to deal with the golfers.

They used to pile sand on the tee to hold the ball until wooden tees came along. I suspect the box with No. 1 written on it was the tee box, a term still used today. My father-in-law had to sweep up the sand and put it back in the boxes on his father's golf course when he was a boy.

Not a square yard of chartreuse and plum plaid polyester to be seen.

Presumably the caddies are the ones carrying the bags; that leaves (apparently) one adult player and a whole gaggle of younger boys. So what's the deal here? What this photo needs is a Lewis Hine caption.

The young man behind the players with his hands in his pockets and the others in the "Caddy Shack" are wearing their official Caddy Badges issued by the Golf Club.
I can't explain the reason for all the other young men gathered around the players.

The tall fellow in the center of the picture looks curiously modern compared to the others. I didn't realize bucket hats had enjoyed such longevity as a fashion statement

See you at the 19th hole!
