library with the Garden, and which provided cooperative relations as 

 regards advanced students. Upon the occupancy of the museum 

 building in 1899 and the equipment of the laboratories, following the 

 appointment on July 1st of that year of Dr. D. T. MacDougal as Director 

 of the Laboratories, twenty students were registered, six of them from 

 Columbia University. Advanced students have been given the privileges 

 of the institution in every succeeding year, and their investigations have 

 covered a very wide range of subjects. Public lectures on Saturday 

 afternoons in the lecture hall of the Museum Building were commenced 

 on April 14, 1900, and during this year seventeen such lectures were given 

 in the spring course and the autumn course. A summer course was 

 added in 1910, lectures being delivered that year on each Saturday 

 afternoon from April 30 to November 19, and they have since been 

 continued from early spring until late autumn. In the spring of 1905, 

 a series of lectures and accompanying demonstrations to pupils and 

 teachers of the public schools was organized, and has been continued 

 during succeeding years. Docentry was organized in 1910, by arranging 

 to provide guidance to visitors to the grounds, buildings and collections 

 on every week day at three o'clock in the afternoon, and has since been 

 continued. 



The botanical exploration of little-known regions was inaugurated 

 in 1898, when Mr. and Mrs. A. A. Heller were sent to Porto Rico, by 

 means of a gift from Mr. Cornelius Vanderbilt, the first President of 

 the Garden. Exploration has been continued ever since whenever funds 

 have been available for this important work, and very valuable addi- 

 tions have thus been made to knowledge and to the permanent collec- 

 tions of the Garden, over 100 trips and expeditions having since been 

 carried out. 



During exploration work accomplished in Jamaica, it was found desir- 

 able for the Garden to have a temporary station on that island; in 1903, 

 the buildings at the Cinchona Botanical Station of the Jamaica Govern- 

 ment, located at an elevation of about 5,000 feet in the Blue Mountains, 

 was rented for a term of ten years, at the rate of 60 pounds annually, 

 the rental being used by the Jamaica Government for the upkeep of the 

 establishment. Students from the Garden and from other American 

 and British institutions were given the privileges of this station during 

 these years, and it served an excellent purpose as an exploration base. 

 At the end of the ten-year period, the British Association for the Advance- 

 ment of Science took over the rental and is continuing this station as a 

 botanical laboratory.
