  I heard today from Mrs. Bridge that
two pairs of Purple Martins nested last summer in
the boxes at Hildreth's Corner, Concord, on Capt. Dakins'
place I think she said. There was a single pair 
there (or perhaps in Mr. Mason's grounds on the
opposite side of the road) in 1905 but no Martins
nested in this locality in 1904. 
Return of the Martins to Hildreth's Corner, Concord.
  A still larger number of Martins bred in the village
of Concord in 1906. On September 9th of this year
Mr. Reginald Heber Howe Jr. wrote me as follows:
" I met Samuel Hoar on my way back from your
attractive cabin, and he told me that at least
six pairs of Martins nested in his box last spring-
he could not be sure of how many more but at least
that number. This is about what I should have
gleaned from his brother Jack's remarks" (of which
Mr. Howe had previously said something to me)
Their return to the village of Concord
  Under date of September 11, 1906 Mr. Howe wrote
again as follows: "I have just stopped at Dakin's
on my way home from town. He had at least two 
pairs in the southerly box. They came late in May
and raised their young successfully. Mr. Mason
opposite had one pair. Does not their coming so late
suggest more birds for the colony?"
