THE BIRD CENSUS. 
Scarcely any one line of nature study carries so 
many interesting and important features as that con¬ 
nected with actually keeping track of the number of 
birds in a neighborhood with a view to increasing the 
more desirable species in every way possible. The 
best method of making a bird census is to count the 
nests in a certain district as soon as the leaves fall in 
autumn. 1 People generally would find it interesting 
to do this for their city Jots or door yards, and if they 
would send the results from year to year to their local 
bird club, to some bird magazine, or to the writer, 
most valuable data might be gathered as to the hoped for increase of 
our native birds in different parts of the country. It is helpful for
