inscriptions reading, in the upper left corner, "Advice Note", and in the upper right corner, "Free, by order of the Post Master General."

One further official variety is somewhat unusual. The American Philatelist for September, 1889,[247] says:—

"We are indebted to Donald A. King ... for information concerning what is certainly a novelty in the postal line, namely, an unpaid letter stamped envelope. When a letter is returned from the dead-letter office the sender is required to pay the regular postage and these envelopes have been prepared of various values. The only one we have seen is the 3 cent value. It is about 175 × 120 mm., and is made of manila paper. In the place for the stamp is a figure 3 about 23 mm. high. In the left hand upper corner RETURNED DEAD LETTER; in the lower corner—

POST OFFICE DEPARTMENT, CANADA,
DEAD LETTER OFFICE.

On the reverse, The enclosed Dead Letter is returned by order of the Postmaster-General for the reasons thereon assigned. The following values are said to exist:

3cents, black onmanila.
6cents, black on?
9cents, black on?
12cents, black on?
18cents, black on?

We have no further information concerning them.
