total number of nesting pairs. Indeed, the gain in this latter respect. 

 69 per cent in the five years, is more than may be explained by 

 the growth of bird food and shelter on the place and is probably due 

 to the entire freedom from disturbance which the birds have come 

 to recognize.

It is interesting to note the change in the character of the bird 

 population from year to year. While -42 kinds of birds nested on 

 the place in the course of the five years, the greatest number in any 

 one year was only 34. while each year a dozen or more kinds of birds 

 nested within sight of the 50 acres, but not within the enumeration 

 area itself. (See Table IV.)
