Concord, Mass.
1909.
May 4
  As I was at work with three of my men in the
flower garden at the rear of our farm house this forenoon
a Chipping Sparrow appeared closely pursued by a female
Sharp-shinned Hawk. As the Chippy was passing over
the top of a large apple tree it suddenly closed its
wings and dropped down through the upper tier of branches.
The Hawk attempted to follow but was stopped by the
interlacing twigs. Mounting upward again it circled
about the tree and then dashed in from one side
driving the Chippy out & into the next tree. As it
again circled it passed over me within 20 ft. when
I flung my cap at it and shouted. It kept on without 
appearing to notice me but just before entering the
tree top turned back and soaring upward in circles
to a great height drifted off to the westward. I
doubt if it would have got the Chippy had I not interfered.
I saw it drop its legs twice apparently from under the tail although
I am not sure about this.
