In order to show the relation between the return of birds from the 

 south and the vernal change in the vegetation, I give the following 

 dates of the leafing and flowering of plants at Mt. Carmel, as noted 

 in the spring of 1872. 1 They hardly show the usual time of these 

 species, for the season happened to be one later than usual.
