breast that properly belongs to neither parent. The origin of this 

 hybrid is not known. Individuals of this race are known to attain 

 the weight of eight pounds each. 



That a variety so obviously a hybrid should thus be known to 

 reproduce itself with so much exactness, may perhaps be taken into 

 consideration in connection with Anas maxima. It is very different 

 in plumage from that bird, and so far is suggestive that the origin of 

 the latter, if a hybrid, must have been different. But its remarkable 

 reproduction of children of uniform coloration with their parents is 

 also suggestive that the maxima may, after all, have been a wild 

 hybrid of some unknown origin, and in like manner able to repro- 

 duce its own peculiar combination of form and colors. Nor is it safe 

 to argue that its size necessarily proves an original parentage as 

 large as itself. The race of hybrids between the Canvas-back and 

 the Mallard, in Carlisle, was nearly twice the size of either parent, 

 and this is equally true of the Cayuga.

 J. L. LeConte, M.D. 



In the summer of 1870 I visited Mt. Washington for a couple of 

 days, but became convinced that the favorable season for collecting 

 Coleoptera there was much earlier than the middle of August, as very 

 few beetles were to be seen. 



Last summer I had an opportunity to go again, and started earlier, 

 though not as soon as I desired, and, as I believe, two weeks late for 

 the best collecting. I reached the mountain on the 19th of July, 

 camping a short distance below the Half-way House, as Mr. Sanborn's 

 old camp among the rocks appeared too bleak, and was on the
