Gentlemen ;

This letter is written to insure a definite understanding relative to the dimen-
sions of the smaller backboard which was legalized at the last meting. I am
sure there is no question about the general size and shape of the board but we
ought to have a definite understending about some of the minor details. I do
not desire to assume unwarranted authority in this matter, but it is essential
that schools and manufacturers have definite information relative to detailed .
dimensions. I have already had many inquiries from sehools and from manu-
facturers. ;

Here are the dimensions as I understand the wishes of the Committee. These
have been checked with experimental boards which were in use the past season +
and, as far as I know, they are such as to facilitate ease of manufacture and
maximum usability. If there is any question in your mind about any one of
these dimensions, I wish you would let me have it by return mail. If I do

not hear from you, I shall assume that these are the sanctioned dimensions.

l. The over-all width is 54 inches. The sides are to be straight lines per-
pendicular to the floor. The lower corners are on & level with the ring. The
top is the are of a circle with a radius of 29 inches and with a center three
inches above the level of the ring. The board is to extend three inches below
the level of the ring at the extreme outside edges of the ring. The part behind
the ring isto b e cut out to as near eighteen inches in width as it can be mde
and still leave a reguler curve to avoid any sharp corners on the lower edge

of the board. Th@ wkti-mels- straight edges at the sides of the board, approx-
imtely 13 3/4 inches in length. All corners and edges are to be slightly
rounded. :

‘This is the board which was sanctioned by mail vote of the Committee for experimental
purposes after the 1939 meeting.

Unless I receive suggestions to the contrary, I will have blue prints made up
along these lines end supply each member of the Committee.

Yours truly,

WU heolev
