Dwinal, Mechanic Falls Me., red "Shanghae Paid C AP 8 64" circular datestamp, "Shanghae C AP 8 64" and blue "Hong Kong C AP 13 64" backstamps, red "1/9 ½" and "1/10 ½" rates, red London Paid datestamp (Jun. 2) and "21 Cents" credit handstamp, full clear strike of "Portland Me. Am. Pkt. 24 Paid Jun. 17 1864" 24c integral-rate datestamp applied at the Portland exchange office. Unlike the ports of Chicago, Boston or New York, it is very scarce to land and exchange through the Portland P.O., and particularly so for the China mails.
