80 REPORT OF NATIONAL MUSEUM, 1920. 



Dr. Abbott himself has continued his own personal explorations 

 in the island of Haiti. He visited Santo Domingo in July, 1910, and 

 remained until the early part of October, collecting in the vicinity 

 of Sosua, on the north side of the island, and later at Saona Island 

 in the Samana region, and at Lake Enriquillo. Early in 1920 he left 

 for Port an Prince, Haiti, accompanied by Mr. Emery C. Leonard, 

 aid iu the division of plants, who was to attend to the botanical 

 collecting. They first visited Gonave Island and then returned to 

 Port an Prince, making collections in that general vicinity. The 

 held work, which was not concluded at the end of June was pro- 

 ductive in yielding excellent material from a region in which very 

 little collecting has been done during the last hundred years. 



Dr. C. D. Walcott, Secretary of the Smithsonian Institution, inci- 

 dental to his geological explorations in Alberta, Canada, paid con- 

 siderable attention to the recent animals as well with the result that 

 a number of valuable mammals, including a Rocky Mountain goat, 

 and a collection of about a thousand specimens of land and fresh 

 water mollusks were added to the national collections. Mrs. Wal- 

 cott, who accompanied her husband, contributed a number of plants 

 which form the basis of her paintings of the wild flowers of this 

 interesting region. 



Several botanical expeditions have been undertaken during the 

 3 T ear in cooperation with other agencies bearing most of the expenses 

 of the field work. Thus, Mr. Paul C. Standley, assistant curator 

 of the division of plants, spent approximately ten weeks in Glacier 

 National Park, Montana, securing data for a handbook of the plants 

 -of that region to be issued by the National Park Service. About 

 4.000 herbarium specimens were secured, besides extensive notes 

 upon the plants and a large series of photographs. Mr. A. S. Hitch- 

 cock, systematic agrostologist, Department of Agriculture, and cus- 

 todian of the section of grasses in the division of plants, devoted 

 about four and one-half months, beginning October 1, 1919, to 

 botanical exploration in British Guiana, under the cooperative plan 

 of exploration entered into with the New York Botanical Garden 

 and the Gray Herbarium of Harvard University, as detailed in my 

 report of last year. Special attention was given to the grasses, of 

 which 30 sets of 108 specimens each were collected, but about 4,400 

 specimens in other groups were also collected. Mr. William Iv. 

 Maxon, associate curator in the division of plants, and Mr. Ells- 

 worth P. Killip, aid in the same division, spent about ten weeks 

 from February to April, 1920, in botanical exploration of Jamaica, 

 cooperating with the Gray Herbarium of Harvard University, the 

 New York Botanical Garden, the Field Museum of Natural His- 

 tory, Chicago, and the University of Illinois. Sets of woody plants 

 and orchids will be sent to the Arnold Arboretum of Harvard
