Courant reported that Plimpton Manufacturing Company was now shipping large quantities of stamped envelopes

This report indicates that Plimpton Manufacturing Company is beginning to get up to speed on the production of stamped envelopes -- or at least that the Courant believed it was.

The Courant did not specify the number of envelopes being shipped each day, but presumably it was higher than 500,000.

1. On October 24, 1874, the Courant reported that Marshall Jewell had signed an emergency contract to increase the supply of stamped envelopes.
2. The Plimpton Manufacturing Company received an order for over 400,000 stamps on October 27, 1874.
3. On October 28, 1874, the Plimpton Manufacturing Company fulfilled the order for 400,000 envelopes and received a new order for over 308,000 envelopes.

1. The Plimpton Manufacturing Company partially fulfilled the order for 308,000 envelopes on October 29, 1874.
2. George W. Casilear left Hartford for Washington, DC, on October 29, 1874, following his examination of the dies and stamp proofs at the Plimpton Manufacturing Company.

The Courant will report tomorrow that Plimpton Manufacturing Company’s output had increased to 900,000 envelopes every ten hours.

The article that refers to the examination of dies and proofs names “Mr. Casilear, artist and expert of the treasury department” as conducting that examination.  According to the interweb, George W. Casilear was a security engraver who worked for the US Treasury.  His brother John W. Casilear worked as a banknote engraver, although not apparently for the US government.  Hence, my bet that the “Mr. Casilear” dispatched to Hartford by Marshall Jewell was George, not John.
