Dear Mr. Allen,

From our previous correspondence with you we know of your interest in
certain matters relating to the game of golf. We are writing now to ask if
you would like to have copies of certain photographs made by the new multi-
flash method in use in the laboratory of A. G. Spalding & Bros. Inc. at
Chicopee, Mass. This method, as you probably know, makes possible very
brief exposure times which provide clear definition of golf clubs moving at

high speed.

Here is a brief description of the pictures we would like to send you:

1. Photograph of a kink produced in the shaft of an iron club
by & half-topped shot, showing the progression up the shaft,
culminating in a slap against the player's hands.

2. A series of pictures showing various stages of the contact
between a wood club and a ball. In these you may clearly see how
the ball is first compressed, then regains its shape, and bounds
away from the face of the club.

3. Two complete swings in multi-flash making possible certain
comparisons between my swing and that of a typical so-called
“average golfer."

Each photograph or set is accompanied by an explanation or interpreta-
tion of it.

If you will merely indicate to us your desire to have these pictures
we shall be glad to send them, of course, without charge.
