In remitting by mail the safest means are a Post-office or Express
Money Order, or a Draft on a New York Bank, payable to Dick &
Fitzgerald. When these are not procurable, Cash (or a Postal Note)
should be sent in a Registered Letter. Unused United States Postage
Stamps, of the denomination of Ten Cents or under, will be taken as
cash in amounts less than One Dollar. Soiled Stamps, Postage Stamps
other than those of the United States, and personal checks or drafts on
local banks cannot be accepted.
