They migrate leisurely southward, and I once followed them, and record- 

 ed their movements from Wood's Hole, Massachusetts, to Jacksonville, Florida. 

 This is the only swallow which lives within the limits of Eastern North 

 America in winter. 



Can any one tell me why nearly, or all, swallows place their nests in 

 sheltered situations ? 



EXPERIMENTAL LESSONS 



LESSON ON CORAL IN AN EIGHTH GRADE 

 GLIXES SCHOOL, SOMERVILLE, MASS 



BY 



M. Eva W abbes - . 



My class were delighted the afternoon Mr. Maynard 

 came to give them a lesson. He was no stranger to the 

 children, for they knew it was he who had lent them so 

 many interesting specimens. 



Their last science lessons had been upon coral polyps, 

 and the different species of coral; so Mr. Maynard con- 

 tinued the subject to reef building. 



He first showed them a head of coral formed into 

 the cup shape, which so well illustrates the development 

 of an atoll. Then by careful questioning he led them to 

 think out the development of the reefs, adding many in- 

 teresting points including some personal experiences. 



The following day I had a review of the lesson in 

 the form of a recitation ; later the children wrote and 

 illustrated it. 



Thinking that Mr. Maynard would be interested in 

 the results, I sent the set of papers to him. The illus- 

 trations and the exercise given were selected by him. 



[Although the method by which the lesson was giv- 

 en to Miss Warren's class was entirely new to the chil- 

 dren, their papers show that they readily comprehended 

 the ideas which were drawn out by the questions asked.
