"Sir, Your telegram of this date is at hand. Our postal card machinery at Castleton is running and we expect to produce from a million to a million and a half per day. This last quantity should carry us with a surplus of from five to eight million after the October deliveries are completed.
We have been informed by your postal card agent that he would want to remove his clerical force from Holyoke to Castleton the 15th or 18th inst and by that time we should have sufficient stock accumulated to meet his wants.
The Postal Card factory is completed. The vault and clerical rooms will probably be finished next week but in any event we will have suitable provision for your clerks as soon as they arrive. We have paper for about ten million cards and about one and a half million daily coming in. This latter can be increased should it be found necessary.
Should our daily report of tomorrow from the mill show any material variation from above we will advise you at once.
We are printing from new plates. Yours Very Truly, Woolworth & Graham, Very Fine.
