NATURALIST’s MONTHLY REPORT. 
How sweetly nature strikes the ravish’d eye, 
Through the fine veil with which she oft conceals 
Her charms in part, as conscious of decay. 
DURING the last month, betwixt the 19th of September, and the 19th of October, the 
woods have been gradually assuming their rich autumnal colours; and at the time I am 
writing, they are in, probably, their greatestbeauty. The leaves of many of the trees are be- 
ginning to fall, and several of the limes and ash trees are already nearly stripped. 
The weather has been warm, and except a few of the nights about the 20th of September, 
and last night (the 18th of October,) there has been very little frost. During several nights, 
about the 10th, there were heavy fogs. Since the full moon, however, the days and nights 
have both been more clear. The wind has blown chiefly fromthe south-west, west, and northe 
west, but last night previously to the frost, it veered round to the east. 
Sepcember 24.——In consequence of the late severe frosts, the flies are become so torpid that 
their feet stick to the windows as though there was something glutinous upon the glass; and 
it is not without considerable difficulty they are able to walk. On turning over Mr. White's 
Observations on Natural History, [ find aremark on this subject so interesting, that Iam in- 
duced to transcribe it. ‘* It has been cbserved that divers kinds of flies, besides their sharp- 
hooked nails, have alsoskinny pulms, or flaps to their feet, whereby they are enabled to adhere 
toany smooth bodies, and evento walk on ceilings, with their backs downward, by means of 
the pressure of the atmosphere on these flaps; the weight of which they easily overcome ig 
warm weather, when they are brisk andalert. But, in the decline of the year, this resistance 
becomes too mighty for their diminished strength; and we see flies labouring along, and Iug- 
ging the.r feet in windows asif they stuck fast tothe glass, and it is with the utmost difficulty 
they can draw one foot atter another, and disengage their hollow caps frorfi the slippery sure 
face. Upon the same principle that files stick and support themselves, do boys, by way of 
play, carry heavy weights by only a piece of wet leather at the end of a string, clapped cluse 
on the surface of a stone.”
