As most of our readers know, we give in our December number, as a frontispiece to the whole volume, a portrait of some one of our distinguished living horticultural authors. We shall have in the December issue of this year the portrait of the author of one of our most popular works on rose culture, which we think will be fully appreciated. The demands for our December numbers are always great - the portrait and full index being given of late years in addition to the reading columns, and outside of the regular subscription price of the magazine. When the publisher first gave this addition, it was in place of the useless "chromos" then popular. They have had their little day, while the Gardeners' Monthly's gift to its subscribers is yearly more and more appreciated.
