Mr. William B. Harison,
3 East 14th Street,
New York City,
Dear Sir:
Some time since we received at the Bureau a package of your new adjustable book covers. You ask whether I consider the device of value for public school use as it has been recommended on the grounds of sanitation. Ithink that the point is well taken, and the simplicity and ingenuity of the device is something astonishing to a person who has often experimented on the proper form for a convenient book cover. It deserves to come into general use where book covers are used.
Very respectfully,
Commissioner.
