Teachers have tried every device possible during the last year to mount 
their Bird Plates in a manner convenient for use. We have now done this for 
them. One hundred and forty-five bird plates and three plates of eggs, 
including fifty-four different species, are put up on eighteen sheets of heavily 
coated manila paper, linen enforced, with covers, 24x32 inches, and tripod 
holder. 
The groupings are original and adapted for class work. Each bird is 
grouped according to place where usually found, or to some peculiar charac- 
teristic. 
They are as follows: 
Plate 1, Birds of Prey. 
“2, Birds of the Tropics. 
“3, Birds of the Wood 
“ 4, Game Birds. 
« 5, Field Birds. 
“ 6, Meadow Birds. 
“1, Wading Birds. 
«« 8, Marsh and Shore Birds. 
“9 and 10, Swimming Birds. 
Plate 11, Birds of Peculiar Beauty. _ 
“12, Birds of Peculiar Habits or Song. 
13, Song Birds. 
14, Warblers. 
15, Finches. 
16, Familiar Birds. 
~17, Tiny Birds. 
18, Miscellaneous, including three 
Groups of Eggs. 
There are from six to ten subjects on each plate, atranged in artistic 
manner. On the third cover-page of Chart is presented a complete outline, 
giving each bird in alphabetical order, its common and scientific names, and 
its number according to the check list of the American Ornithologists’ Union. 
For further information write for circular.
