" Exhibition of a Specimen of Stangeria" by Mr. G. V. Nash ; 

 November 3, "Notes on Some Interesting Fungi," by Dr. 

 W. A. Murrill and Mr. Fred J. Seaver, "Flora of the Cuban 

 Keys," by Dr. N. L. Britton; December 1, "Relation of 

 Organic Matter to Soil Fertility," by Mr. E. D. Clark, 

 "Distribution of Actinofihyllum in the West Indies," by 

 Mr. R. C. Schneider. In addition to the regular outlined 

 programmes numerous notes and discussions have been 

 offered by various members of the staff. A synopsis of 

 each of the papers and discussions brought out in these 

 meetings has been published in the Garden Journal. 



Meteorological Records 



Meteorological records have been kept as usual through- 

 out the year. In order to make these records more perma- 

 nent and to save time in looking up back records a new 

 blank has been prepared of the proper size to be bound in 

 book form at the close of each year. This blank provides 

 space for a report of the condition of the weather for each 

 day throughout the year as: "clear," "cloudy," "rain," 

 etc., with the amount of precipitation for each day and 

 total for the month, maximum and minimum temperatures 

 and mean temperature for the month. The records have 

 been kept in this form through the entire year and during 

 the brief intervals of my own absence from the Garden the 

 records have been made by Dr. W. A. Murrill. 



Personal Investigations 



My own investigations have been carried on in accordance 

 with the plan outlined in previous report, 

 with culture work with the fungi, my 1 

 called to the occurrence on heated soil of certain fungi 

 which normally occur in nature on burnt ground. Investi- 

 gations have shown that this is apparently due to some 

 chemical change brought about in the soil by heat. One 

 paper has been published on this subject: "Studies in 

 Pyrophilous Fungi — I: The Occurrence and Cultivation of 

 Pyronema."
