The scientific program was then carried out. Dr. Marshall 

 A. Howe spoke on "A Visit to Porto Rico for Collecting Marine 

 Algae," referring to an expedition in June and July of the present 

 year, undertaken as a part of the general natural history survey 

 of this island that is being carried on by the New York Academy 

 of Sciences, the American Museum of Natural History, and the 

 New York Botanical Garden, with financial cooperation of the 

 insular government of Porto Rico. Special attention was given 

 to dredging operations, with Ensenada, on Guanica Harbor, as 

 a base. Specimens were exhibited, particularly of the genus 

 Caulerpa, of which nine or more species occur in or near Guanica 

 Harbor. Photographs, also, were shown. A more detailed 

 report of this expedition is published in the Journal of the New 

 York Botanical Garden for October. 



Mr. R. S. Williams followed with a paper on "A Species of 

 Sphagnum native to the New York Botanical Garden." He 

 said in part: " Sphagnum palustre L. or S. cymbifolium, as it is 

 more commonly known, is a cosmopolitan species. It has been 

 found at no great distance on both sides of the Botanical Garden 

 but apparently not recorded before from within its limits. 

 The depauperate, dull green specimens, with tallest stems about 

 4 cm. high, occurred in a rather damp shaded ravine in three very 

 small, separate tufts near stumps or. decayed wood. 



Some of the specimens, collected October 17, were exhibited, 

 along with other well-developed forms, the most robust and 

 finest in North America coming from the vicinity of Mt. Tacoma, 

 Wash." 



B. O. Dodge spoke briefly on the subject "Botanical Observa- 

 tions at Camp Columbia, Bantam, Connecticut." Specimens 

 and photographs of several species of fungi collected in this 

 region were exhibited. Attention was called to a form evidently 

 causing a heart rot of the apple trees. Polyporus admirabilis 

 Peck was found growing on living apple trees at a number of 

 different localities. One specimen was eighteen inches in 

 diameter. A specimen of Amelanchier canadensis growing on 

 the grounds of Camp Columbia was found to measure nine feet 

 in circumference.
