large number of species and varieties at such times as we are 

 ready to receive them. Mr. Palmer's offer also includes 

 specimens of many hardy ferns, of which he has a note- 

 worthy collection. The total number of kinds of hardy trees 

 represented in the Garden, including those native to the tract, 

 is over 290. The care of the planted specimens has re- 

 quired the work of one gardener and one laborer for about 

 one-third of their time. 



5. Viticelum. The vines and trailers brought together on 

 the rough arbor east of the Museum Building have been cul- 

 tivated and trained, and many of them are now of consider- 

 able length. The number of species represented is 62. 

 Their care has required the attention of a gardener for a few 

 hours a week. 



6. Nurseries. The plan relative to the nursery work re- 

 ferred to in my report for the preceding year was carried out 

 in the spring, the first nursery planted being abandoned and 

 its contents transferred to other plantations. The work was 

 then concentrated on about two acres of land immediately 

 south of the propagating houses on the east side of the 

 grounds, part of this area being devoted to herbaceous plants, 

 part to deciduous trees and shrubs, part to conifers : the cold 

 frames were set immediately in front of the propagating 

 houses. The work of propagation and experimentation both 

 out of doors and under glass, is thus all brought together and 

 is conducted by the same men ; one foreman gardener, one 

 apprentice and one laborer have been required, with a few 

 days occasional additional help from a fourth man. The 

 propagating houses are thus operated as a part of the nur- 

 series. In addition to the care of several thousand young 

 plants, cuttings and bulbs, brought into the nurseries from 

 various sources, over 6,000 packets of seeds were sown ; 

 these were obtained by exchange from other botanical gar- 

 dens, by gift, and collected by our several exploring parties. 

 From this source we now have about 10,000 young plants for 

 distribution during the next year among various permanent 

 plantations, or for exchange with other institutions. The
