NOTES AND COMMENT 



The advance sheets of the Atlas of American Agriculture are now 

 appearing rapidly under the supervision of Dr. 0. E. Baker. Particular 

 interest attaches to the first section of the climatic part of the Atlas on 

 Frost and the Growing Season. Maps of the United States, on a scale 

 of 130 miles to the inch, are given to show the average dates of the last 

 and first killing frost, and the average length of the frostless season. 

 Smaller maps show departures from the normal length of the frostless 

 season and the percentage of probability of such departures. Useful 

 as the Atlas promises to be, there will always be a small but important 

 group of workers who will need the data on which the maps are based 

 even more than they need the maps themselves. 



The Macmillan Company have recently pubhshed a Manual of Vege- 

 table Garden Insects, by C. R. Crosby and M. D. Leonard. The life- 

 histories and methods of control of injurious insects are grouped accord- 

 ing to the plants which they attack. The book covers the United States 

 and Canada and is designed to meet the needs of the practical grower 

 of garden crops. 



The equipment and work of the Swedish Forest Research Institute, 

 near Stockholm, have been described in one of the series of contributions 

 published by the Institute. It was established in 1907, maintains a 

 staff of six men and is admirably equipped for all lines of forest 

 investigation.
