y6 NATURE-STUDY REVIEW [7:3— Mar, 1911 



Interest in the window box, the hotbed and the selection of gar- 

 den seed is timely. The lawn deserves attention and trees should 

 be pruned. The first of the trees unwrap their buds, and the 

 earliest of the spring flowers appear. A few hardy insects 

 emerge from winter quarters. The dog and the horse are shedding 

 their cold weather coats. On all sides we detect "signs of spring." 

 To summarize, we select out from our March nature notes 

 the following subjects for investigation: 



Migration of birds 



Awakening of hibernating animals 



Spring changes in animal coverings 



Poultry raising 



Opening of winter buds 



Pruning of trees ; the selection of trees and shrubbery 



'Rapid growth of the first appearing herbs 



Maple sugar and the sugar maple 



•Care of the lawn 



Window box, hotbed and cold frame 



The choice of seed ; planning the garden 



Weather studies and astronomical observations
