TO McGraw-HILL Book Company: ING. Dr. Allen ee two oer 11-10-37 electrotype plates in itself is a time consuming job because it is our practice to incorporate the original halftone engravings in our printing plates so as to insure the best possible printing results. Naturally, until the last page proof of the text pages has been returned to the printer approved and ready for printing, I can make no definite promise as to the date on which bound books will be ready, but I do know that we are in a position to give excellent service and that the printer will use two or more presses for the actual printing in order that it be completed at the earliest possible moment consistent with quality and accuracy. Very truly yours, JAH: LOC
