of shrubs in this collection is now 530. It will probably be 

 practicable to materially increase this representation of species 

 during the next year, for it seems probable that the roads and 

 paths in that part of the Garden will be essentially completed 

 during 1903. 



3. Salicctum. The collection of willows and poplars, 

 planted in the meadows and marshes at the northern end of 

 the Garden has been cultivated roughly, and the number of 

 species increased from 43 to 50. 



Here, again, it has not been practicable to plant much land 

 permanently, on account of road and path-building, but this 

 work will probably be largely completed in that area during 

 the next year. 



4. Arborettim. Little addition has been made to the tree 

 collections, on account of the necessity of concentrating work 

 on other departments. The trees already planted have been 

 cared for and a considerable number of additional ones have 

 been set in place, as rapidly as grading operations permitted. 

 Considerable portions of the area about the public conserva- 

 tories, and between them and the Museum Building, set aside 

 for the main collection of coniferous trees, have been pre- 

 pared for them, and much of it can be planted in the spring, 

 the young trees being derived from our nurseries, and from 

 those of Mr. Lowell M. Palmer, at Stamford, Connecticut, 

 whose valuable gift of these plants has already been reported. 

 The total number of species of hardy trees represented in 

 the Garden, including the native kinds, is now about 300, 

 some of which are still in the nurseries. 



5. Viticetum. The rough arbor built on the border of the 

 forest east of the Museum Building, for the purpose of train- 

 ing vines, has served its purpose very well, some of the 

 species now having covered considerable parts of it. This 

 collection is at present somewhat inaccessible, but the carry- 

 ing out of plans for path-building during the next year, will 

 bring it within an easy walk of the Museum Building and 

 the herbaceous grounds. The number of species of vines 

 and trailers grown there during the year is about 60.
