March 11 Monday – Sam’s notebook: “Mr. Mitchell, 7.30 24 W.10th” [NB 44 TS 7].

At 1410 W. 10th, Sam wrote to H.H. Rogers, enclosing Whitmore’s Mar. 9.

Whitmore thinks as within. I sent the Pratt & Whitney letter back to Pratt & Whitney Co, & told them to send their bill to you & you would give it your personal attention. I haven’t heard any more from them [MTHHR 458]. Note: this date seems conjectural and is in brackets in the source. For there to have been enough time for Sam to receive Whitmore’s letter and write to P&W and then say he had not heard any more from them suggests several days had gone by, not just one or two.
