Viticetum. Many of the vines are making a good growth 

 which has necessitated considerable tying up and training. 

 The collection remains essentially as previously reported. 



Nurseries and Propagating Houses. 



A large amount of work, both of a cultural and experi- 

 mental nature, has been conducted here, and the range, one 

 house of which still awaits construction, has been taxed to its 

 utmost to accommodate the demands made upon it. 



Over 6,000 packets of seed have been sown, and from this 

 source have already been obtained and accessioned over 

 8,500 plants. Of these seeds a large number were of trees 

 and shrubs, many of which will require a year or two in 

 which to germinate, so that many more plants will be ulti- 

 mately obtained. 



The conservatory collection has been especially augmented 

 from this source, many interesting and showy species being 

 among the number. Many of the plants are rapidly ap- 

 proaching a size which will permit of their removal to the 

 conservatories. There are about 1,000 species here not repre- 

 sented at present in the conservatories. In addition to the 

 enrichment of the collection, a large amount of duplicate 

 material has also been thus secured which can be most ad- 

 vantageously used in exchanges with other institutions. 



The herbaceous grounds have also been much enriched 

 from the same source, several hundred species having al- 

 ready been removed thence, and many more will undoubtedly 

 follow in the spring from the trial grounds. 



Of the five compartments which at present compose this 

 range, four are devoted to horticultural purposes ; the fifth is 

 intended for experimental work and is run in connection with 

 the laboratories. Owing to the demands of the purely horti- 

 cultural work, it has been necessary to trespass somewhat 

 upon this room, but this has been done only when absolutely 

 unavoidable. The importance of this experimental work 

 has been fully realized, and every facility in the way of 

 plants or assistance has been placed at the disposal of inves- 

 i gators and students.
