few days Martins visited it, and continued to temporarily live at the 

 house up to the date of her report, July 14th. 



Since it requires eight weeks — or longer, — for a pair of Martins 

 to build their nest, incubate eggs and care for the nestlings, we can 

 scarcely expect any of them to start household duties after July 1st, 

 and, in fact, few of them will venture to build their nests after June 

 20th, and I might also add, that many discouraged pairs give up 

 nesting even before this date. 



In the present instance, as well as others, where the Martins have 

 arrived late, but did not attempt to nest, it is safe to say that these 

 birds will return to the new location, early next spring, to breed.

 Dear Sir: 



The bird-house we received from you went into position the 23rd of June. The 

 25th the Martins showed themselves— a pair of them — and they would fly around 

 the house and finally alighted about the 27th. The sparrows almost immediately 

 began to build their nests in the house but by persistance we have kept the house clean. 

 The Martins came every morning and evening, sometimes only females, then again one 

 male with the females. Yesterday one male and female were here almost continually 

 all day. This morning two males and two females took possession and the sparrows 

 are laying low. Do you think they will still build this year? It is rather too late, isn't 

 it? 



Very respectfully yours,

Mrs. M. Piel, New York City, bought a Style 2 Martin House f ot- 

 her summer home at Jackman, Maine, who undoubtedly missed having 

 the Martins to nest by the negligence of the overseer to put the house 

 up in time.

Mr. J. Warren Jacobs, 

 Dear Sir: 



I intended to inform you of our experience with the nice Martin house you sent 

 to us this spring, but we were disappointed. 



When we came here, the first week in June, the bird-house had been erected only, 

 a few days before. 



Our men were reminded to put up the house by seeing a number of Purple Martins, 

 probably on a search for summer houses.
