DELAWARE VALLEY OBNITHOLOGICAL CLUB & 



In the early days of the Club he introduced the members to 

 the lower Susquehanna Valley which he had visited in former 

 years, and later on made tours of Pike and Wayne and Somer- 

 set Counties, Pennsylvania, with C. F. Saunders the well-known 

 botanical author, while with the writer he explored many 

 parts of the New Jersey Pine Barrens. 



In 1904 he visited the Florida Keys with H. W. Fowler, and 

 in 1906 and again in 1908, traveled through the Canadian 

 Rockies with Mrs. Chas. Schaffer, making valuable collections 

 upon which was based his well-known volume on the flora of 

 the region which was illustrated by reproductions of Mrs. 

 Shaffer's paintings. A few years previously he published 

 a handbook of the flora of Philadelphia and vicinity in con- 

 junction with Dr. Ida A. Keller which was largely used in 

 the city high schools. In 1910 Brown accompanied his brother 

 to Jamaica and in 1911 was botanist on an expedition to Trini- 

 dad and Venezuela, organized by Mr. Francis E. Bond, one 

 of his old schoolmates. He also made trips to Bermuda in 

 1905, 1909, 1912, 1913 and 1914 and to Porto Rico in 1915 in 

 company with Dr. N. L. Britton. 



On all of these expeditions valuable collections were obtained 

 which greatly enriched the Academy's herbarium, while Brown's 

 knowledge of plants was vastly extended. The constant care of 

 the herbarium and his devotion to horticulture made him famil- 

 iar with many exotics and the knowledge obtained in the tropics 

 only increased his ability to identify specimens on sight — an 

 ability which he possessed to a reroarkable degree. This sort 

 of botanical knowledge always appealed to him much more 

 than the differentiation of the unlimited races and varieties of 

 the present-day specialist. 



Brown's interest in birds was only second to that in plants. 

 In our school days in Germantown we learned the local birds 

 together and the first specimen of many a species to grace our 

 cabinet was secured by Stewardson. He became thoroughly 

 familiar with all the local species in their various plumages and 

 was a most accurate field ornithologist. We jointly compiled 

 during these years the migration record for Germantown which 

 went to the U. S. Dept. of Agriculture. The D. V. 0. C. was
