BOOK NOTES.

In anticipation of the consolidation of this magazine with _The American

Botanist_ at the end of the year, some very extensive improvements in

the new magazine are to be made. Among the more important are a better

grade of paper, the use of numerous illustrations, and the addition of

enough pages to make it the largest magazine for the price in America.

With the beginning of 1913 a department of ornamental gardening will be

included in which the cultivation of our showy wild-flowers will receive

adequate treatment. This magazine will continue the matter relative to

ferns now appearing in _The Fern Bulletin_ and all manuscripts used will

be paid for. No reader of Fern Bulletin should fail to subscribe for the

new _American Botanist_ if they wish to keep abreast of the times in

botany. Those who subscribe for 1913 before November 20th, will receive

the November issue free.

Messrs. Ginn & Co. have nearly ready for publication a book on Agronomy

by the editor of _The Fern Bulletin_ which should be of interest to all

who have anything to do with cultivating plants. Although the book is

intended as a school book to be used in connection with gardening

courses, the fact that it not only gives directions for planting and

cultivating kitchen vegetables and flowering plants, but explains the

principles upon which such directions hinge, will make it of much value

to the gardener whether amateur or professional. The book, however, is

not a mere gardening manual. It discusses soils and their origin, the

fundamentals of landscape work and plant breeding, and the effects of

heat, light and moisture upon plants in general. There will also be more

than 200 illustrations.

Ferns Weighing a Ton.--In the tropics ferns often attain the height of

small trees, but their trunks are usually so slender that they never are

of any great weight. For the heaviest trunks we must look among lowlier

species, where the circumference of the short trunk in some cases is so

great that immense weights are attained. In Australia and New Zealand

there grows a relative of the common cinnamon fern named _Todaea

barbata_ which quite takes the palm in this respect. The trunks are

great rounded mosses five or six feet high and at least twenty feet in

circumference, most of the upper surface being beset with living fronds.

Specimens have been found with trunks that were estimated to weigh more

than a ton and a half.
