VOLUME VI
Out of Print
It is not likely that there will be any more "last appearances" of
Volume VI. The best we can do now is to begin with volume VII. We offer
the next 13 volumes (7-19) for $9.00 and will present to each purchaser
a copy of 10 year index, Boston Meeting Papers and Ferns of Upper
Susquehanna as well as 3 different numbers of Vol. VI. Single volumes 75
cents.
