. RUR\L SciTOCr. LEAFLET. 8/1 



Have a feather illustrating the type which is being studied. Name 

 the breed or breeds on which it may be found. Describe how it differs 

 from other kinds of feather markings. For this purpose, the black- 

 board and color crayons may be used to excellent advantage, to describe 

 in detail the differences of the feather markings so that the pupils will 

 quickly see the distinction. 



Select certain feather markings, and ask the pupil to name the kind 

 of feather, and state the kind of fowl on which it can be found. 



If the time and the age of the pupils will permit, they should be re- 

 quired to draw at least one feather, natural size, of each of the different 

 kinds of feather markings. 



Place the different kinds of feathers promiscuously together and ask 

 the pupils to separate them into special groups of the same kind of feather 

 marking. 



Call upon certain .pupils to select a collection of feathers of certain 

 markings, then ask the class to verify the result. 



PLANT DISEASES 



A Fungus 

 By H. H. Whetzel 



Object. — ^To help the pupil to discover something about the nature 

 of a fungus. Fungi are responsible for most of the diseases of our 

 cultivated plants. This lesson is for the older pupils. 



Materials. — Pieces of bread cut in inch and a half squares; tumblers 

 and saucers; two inch squares of clean, white blotting paper; some black 

 bread mold; inoculating needle, made by inserting ordinary needle in 

 wooden handle; alcohol lamp. 



The black bread mold may usually be obtained by placing pieces of 

 stale bread, slightly moistened, in a can, jar, or closed dish of any sort, 

 or a bit of mold for a starter may be had by addressing a request for the 

 same to the Department of Plant Patholog\^ State College of Agri- 

 culture, Ithaca, N. Y. 



Method. — I St. Prepare the culture media as follows: Place a square 

 of the blotting paper in the center of each saucer. Moisten with boiling 

 water. There should be no more water in the saucer than the blotter 

 will take up. Place a freshly cut square of bread on each blotter and 

 cover with one of the tumblers. One of these culture dishes should be 

 prepared for every three or four children.
