of winter visitors also, though to a less extent. The fall migration 
has been taken note of as well, and quite full records have been 
made both of arrivals and “lasts” at that season from 1885 to 
1894, and in 1907 and 1908, while considerable though less abun- 
dant observations have been made in nine other years. 
I can generalize but little from my observations, the most posi- 
tive deduction being that a wet spring is liable to be characterized 
by a comparative abundance of sandpipers and swallows. The 
weather also, particularly the prevailing temperature during the 
previous few weeks, has a great effect in hastening or delaying the 
arrival of the late March migrants, and to a lesser extent the arrival 
of those reaching us in April. Thus the year 1915, was unusually 
cold in March and early April, and the early migrants were un- 
usually late, while the opposite was the case with the year 1890. 
In making up the average dates for “first seen”’ and “last seen,” 
abnormally early and later dates have been excluded, as well as 
those in a species must certainly have been here for some time 
before it was actually observed. As however, a bird cannot be 
observed until it is actually present, while it may be overlooked 
even though here, the average dates of “first seen” are undoubt- 
edly to some extent later than the actual average date of arrival 
of the species, while the average dates of last seen are of course 
somewhat earlier, than the actual average dates of departure of 
the different species. 
In all 165 species are included in the following tables, which are, 
I hope, self explanatory.
