resentatives from California and New Mexico, 

 will soon appear in the Garden Bulletin. 



Dr. Earle also exliibited a rosebush from 

 under glass at the Garden, the roots of which 

 have been attacked by a fungus now under 

 examination and cultures of which were 

 exhibited. The mycelium was abundant in 

 the fibrous roots ; also in the bark and cambium 

 immediately above ground, and had caused 

 sudden yellowing and dropping of the leaves. 



Dr. MacDougal recalled the suggestion that 

 potatoes are the result of fungal infection of 

 the underground stem; it is said that no one 

 has ever examined a potato tuber without find- 

 ing fungus traces in it. In many cases of 

 precocious blooming among both wild and 

 cultivated plants, the cause is stimulus from 

 similar infection. 



Dr. MacDougal also exhibited specimens of 

 two remarkable Alpine xerophytes from an 

 altitude of 4,000 feet on New Zealand moun- 

 tains, known as vegetable-sheep, Raoulia and 

 Haastia, composites between which belongs 

 Gnaplialium in order of afiinity. 



Dr. Rydberg spoke of a Rocky Mountain phlox 

 with similar growth in cushion-like masses. 



Mrs. Britton reported on the progress of 

 her studies of a Vittaria collection made by 

 Dr. Britton at St. Kitts, and exhibited draw- 

 ings, and the present indication that two dif- 

 ferent specific names have been in use for 

 different stages of the same life-history.

THE ONONDAGA ACADEMY OF SCIENCE. 



The Academy met in the historical rooms 

 in Syracuse on Friday, Feb. 21, 1902. Dr. 

 W. M. Beauchamp gave the presidential ad- 

 dress on the ' Peopling of Early America.' 

 He gave a resume of the early investigations, 

 touching briefly on the different theories pro- 

 posed, and emphasizing the fact that the an- 

 swer to the problem lies in the researches into 

 the languages, customs and manners of the 

 present nations and the archeological remains. 

 Dr. Beauchamp gave many interesting items 

 from his extended observations on the native 

 tribes of New York State.

DISCUSSION AND G0BBE8P0NDENCE. 



AMERICAN ASSOCIATION FOR THE ADVANCEMENT 

 OF SCIENCE : ANTHROPOLOGY. 



The fifty-first meeting of the American 

 Association for the Advancement of Science 

 \vill be held at Pittsburgh, Pa., on June 28 

 and July 3, 1902. Mr. Stewart Culin, of the 

 University of Pennsylvania, will preside over 

 the Section of Anthropology. 



Anthropologists are cordially invited to at- 

 tend and contribute papers upon subjects con- 

 nected with their fields of research. Several 

 members of the Section have informally ex- 

 pressed the desire that some special effort 

 should be made by the museum and field work- 

 ers of the Section to present papers on the 

 collections of importance with which they are 

 familiar. 



In order that a preliminary sectional pro- 

 gram may be distributed in advance of the 

 meeting, titles of communications should be 

 sent to the secretary as soon as possible. 

 Abstracts of papers, or the papers themselves, 

 may be sent later at the convenience of the 

 authors, who are reminded that no title will 

 appear in the final program until the paper, 

 either in full or in abstract, has been passed 

 upon by the sectional committee.
