though it is most desirable. It should not be introduced to the 

 exclusion of any part of the course, but should be made voluntary 

 work for those showing a taste for it. It should not be limited 

 to learning names of plants, but should be made a study in the 

 plan of classification as well. 



The preparation of an herbarium is not required nor recom- 

 mended except as voluntary work for those with a taste for col- 

 lecting. If made, it should not represent so much a simple ac- 

 cumulation of species as some distinct idea of plant associations, 

 or of morphology, or of representation of the groups, etc. 



The recent report of Gifford Pinchot, chief forester of the 

 United States, shows that about 700,000 trees were planted last 

 year on forests in Nebraska, Kansas, Colorado, New Mexico, 

 Arizona, Utah, Idaho, and California. There are now growing 

 at the planting stations more than 2,200,000 trees, which will be 

 ready for planting in 1909. Sufficient seed was sown in the 

 spring of 1908 to produce 4,600.000 seedlings. 



For the Bulletin of the New York Botanical Garden issued 

 February, 1909, Addison Brown has written an interesting ac- 

 count of the Elgin Botanical Garden, created by Dr. David 

 Hosack, and its relation to Columbia College. The Bulletin also 

 contains a paper on the North American Gill Fungi with a simple 

 key that will be very helpful to many readers of Torreya. Each 

 of the above contributions is also issued separately by the New 

 York Botanical Garden. 



At the first annual conference of the governors of New Eng- 

 land one session was devoted to the planting of trees. Forest 

 trees were discussed, but especial interest was shown in orchard 

 trees. New England, with its convenient markets, low land 

 prices, and large proportion of hilly country not well suited to 

 farming, could easily rank first in the production of apples, if the 

 business were conducted with the energy characterizing western 

 agricultural enterprises and guided by up-to-date methods.
