NOTES AND MEMORANDA. 
The following note from Dr. Arthur 
Hollick was read: 
At our last meeting Mr. Charles P. 
Benedict exhibited a section of an old 
wooden water main, in use in New 
York City until 1835. I was curious to 
know what kind of wood had been 
utilized for the purpose and transinitted 
a piece to Professor E. C. Jeffrey, of 
Harvard University, who kindly deter- 
mined it for me. It proves to be white 
pine (Pinus Strobus L.),-—a tree which 
is not now very plentiful in this vicin- 
ity, although formerly quite abundant.

Mr. Wm A _ Shortt described, by 
means of a series of carefully executed 
sketches, his observations on the suc- 
cessful co-operative efforts of several 
ants engaged in the task of dragging 
the body of a caterpillar over various 
obstacles. 
SPECIMENS EXHIBITED. 
Mr. James Chapin exhibited four 
mounted specimens of the American 
goldfinch [ Astragalinus tristis(Linn.) ], 
to illustrate the male moult. They 
were obtained respectively on November 
6th, 1904, April 8th, 1905, April 22nd, 
1905 and May 18th, 1905. The first 
was in winter plumage and the last in 
full breeding plumage. 
Mr. Alanson Skinner exhibited a 
collection of arrow points, arranged on 
cotton batting, in a shallow glass- 
covered case, in order to illustrate this 
method of displaying them. The speci- 
mens were held in place on the cotton 
by the pressure of the glass cover and 
withstood considerable handling and 
shaking without becoming displaced.
