NOTES AND COMMENT 



An Agricultural Atlas of the United States is being prepared by the 

 Office of Farm Management in Washington, under the immediate di- 

 rection of Mr. 0. E. Baker. The Atlas will exhibit cartographically 

 the latest statistics of crops, live stock, forest products, and farm prop- 

 erty, and will show the distribution of areas under irrigation or dry 

 farming. An entire section of the Atlas will be devoted to climate, 

 and it has been carefully planned to exhibit just those aspects or in- 

 tensities of climatic conditions which are of importance to vegetation 

 and to crops. There will also be a section devoted to hypsometric, 

 geological, soil and other physical maps. The completed Atlas will be 

 of great usefulness in educational and research work, as well as for 

 reference. 



A tract of land near Greenfield, New York, has been given to the 

 state for the purpose of preserving a large ledge of fossil algae situated 

 upon it. A shelf of Cambrian limestone has been planed off by glacial 

 ice so as to expose sections of Cryplozoon, a hemispherical calcareous 

 marine alga. The tract will be named Lester Park, in honor of its 

 donor, and it will be noteworthy as the first fossil botanical garden — ■ 

 although it is by no means the first fossilized botanical garden.
