Notes — Here and There

The Tennessee Ornithological Society gave an ornithological exhibit 
in the Art Hall of the Nashville Carnegie Library throughout the month 
of April. Its purpose was to illustrate the work being done by the Audu- 
bon Societies and to educate the public to the attractiveness of bird study 
as a recreation. A comprehensive exhibit included many hundreds of 
mounted birds, skins, nests, eggs, books, pictures and bird boxes. The 
T. O. S. is now closing its seventh year. 
Approximately 15.000 binoculars and field glasses were recently sold 
at retail, by the Government at attractive prices, through The Ordnance 
Salvage Board, Frankford Arsenal, Philadelphia, Pa. Notice of future 
sales, if any, will be given in this column if the information can be 
gotten in time. 
The Biological Survey is experimenting with the use of poison gasses, 
developed during the war, for exterminating noxious birds and rodents. 
Large roosts of English Sparrows exist in and about every city; the 
writer knows of one extensive hawthorn thicket, in the outskirts of his 
home town, which is used nightly, throughout the winter, by perhaps 
half a million sparrows, grackles aud cowbirds. Marsh roosts of west- 
ern blackbirds, prairie dog towns and fields infested with spermophiles 
are among the possibilities for this method of control. 
The Secretary has just returned from a trip which comprised six- 
teen interesting days in the Cumberland Mountains and on the upper 
Cumberland River, in Tennessee. Active field work enabled him to rec- 
ord observations of considerable interest as well as to add some choice 
specimens to his collection. Incidentally, the trip is his alibi for the 
brevity of these notes.
