5. West Ghester County Cabinet of Natural Science-—By the 
5th report it appears that the Institution is in a flourishing condition ; 
that its collections in several branches of Natural History particular- 
ly Botany, Mineralogy and Conchology are already very considerable 
and increasing ; its herbarium contains about 4000 specimens, 3000 
of which are presents from abroad ; it has a collection of coins, and a 
telescope which formerly belonged to General Anthony Wayne, pre- 
sented by his son, Isaac Wayne, Esq. 
The collections of the Society are, from time to time, increased by ~ 
the public spirit of our naval officers and others who travel abroad. 
A considerable number of original papers on subjects of Science 
has been contributed by members of the society. 
6. Destruction of Birds by starvation. 
Extract of a letter to the Editor from S. Woodruff, Esq. dated Windsor, Ct. 
i 1832. 
Among other effects produced here by the late unusually cold 
weather, it may be thought worthy of notice that swallows and some 
other small birds which feed principally on flying insects have, in 
vast numbers, perished by hunger. Between the 6th and 28th days 
of May, 14 barn swallows were picked up in and about one barn in my 
neighborhood ; and I am credibly informed that at many other barns 
in the vicinity, from ten to fifteen, in each barn, were found in a like 
condition. Several hundreds have perished in the single town of Gran- 
by. By reason of cold the insects continued in a torpid state, and 
afforded no opportunity for the birds to come in contact with them. 
About the 12th of May (eight days later than their usual period) 
the martins appeared ; but finding little or no food, soon disappeared, 
and for the twelve or fifteen days following none were seen, and up 
to the present time but few have returned. 
About the 10th of May several flocks of wild geese passed over 
on their return to the south. .
