THE PLANT WORLD. 
position of Greenland, and the similarity of conditions there with 
those of the northernmost part of this continent must necessarily 
appeal to Americans, and until the time arrives when a permanent 
biological station can be established in a suitable locality in 
Alaska, those engaged in arctic work will find the now proposed 
institution a place of interest.”—Pehr Olssen-Seffer, in Science, 
February 3, 1905. 
The Second Annual Meeting of the American Breeders’ 
Association, under the Presidency of the Honorable Secretary of 
Agriculture, James Wilson, was held at Champaign, Ill., February 
1, 2 and 3, 1905. Especially prominent in point of importance 
were the several papers dealing with the breeding of strains of 
plants resistant to disease. This indicates that intelligent atten¬ 
tion is being given to the problem of ‘ preventive medicine,’ if 
we may so denominate it, in the plant kingdom. The theory 
of heredity too occupied a goodly share of attention. The Asso¬ 
ciation, though young, promises to become a permanent and 
important institution. There are already between four and five 
hundred members. 
The publication of School Science and Mathematics , tem¬ 
porarily discontinued since last summer, has been resumed under 
the editorship of Charles H. Smith, of the Chicago High Schools. 
There are six departments represented, of which one, that of 
Biology, is edited by Professor Otis W. Caldwell, State Normal 
School, Charleston, Ill. Vol. 5, No. 1, January, 1905, has ap¬ 
peared and contains the following papers of interest to teachers 
of botany. ' Apparatus for the Measurement of the Growth of 
a Plant,’ by G. W. Low; 4 Report of Committee on Biology ’; an 
'Aquarium’ (of Simple Construction), by W. W. Whitney; 
‘ Is Silphium perfoliatum a Carnivorous Plant ?’ by N. A. Harvey; 
and ‘ Bacteriology in the Public Schools,’ by W. H. Manwaring. 
We are informed that from, now on The Mycological Bulletin 
will be published at 25 cents a year instead of 10 cents as here¬ 
tofore. The size has, however, been increased from twelve to 
twenty-four numbers a year. Subscriptions should be sent to 
Professor W. A. Kellerman, Columbus, Ohio.
