My dear Mr. Brev/ster:- 
Thank you for your kind note and enclosure. I hope 
when you get out to Concord you will drive up and see the Museum 
and the faunal papers. 
As to the crayfish I have the following; George Warren caught 
one there last autu n and exhibited it in John Keyes window alive. 
He put it back in the Pond. Last summer Wells Blanchard caught 
one when swimming but left it in the Pond. Neal Wainwright also 
when swimming saw two or three. Apparently they inhabit the bar 
off Tlioreau's cove. They could not have been there I suppose in 
Thoreuu's time, nor until fairly recently, yet I so far have been 
unable to hear that any were ever put in the Pond.. In the spring 
I shall go in search of one, and if it bartonii I suppose it is 
not improbable that they are here, this far east of Worcester Co. 
where they are reported. If of a western variety their presence 
is probably due to a fisherman's bait box. I will report what I 
find in the spring. 
You rs ve ry t ruly
