a walk of less than a mile and a half, and 

 in but little more than an hoards time. 



And this, quite ahead of the season 

 also; the walk we have described having 

 been taken in April, as stated, with results 

 precisely as here set down. 



Let anyone cover the same course at 

 the same hour one month later and he 

 will meet from two to three times as many 

 varieties among the feathered songsters 

 he seeks, provided, of course, he knows 

 how to go about it. 



For then the Thrush family, and Swal- 

 lows, and Orioles, and Wood Warblers, 

 and Vireos, and Flycatchers, and Pewees, 

 and many others will have arrived once 

 more, to make field and hedge and blue 

 sky, and the thick growth of new timber — 

 by that time a mass of fragrant foliage — 

 just as glad as ever before, in vernal days 

 gone by.
