this to make a chart for class use in studying the points of the dairy 
cow. Sketch winter birds and winter scenes on the farm. Make 
plans for any constructive work at home. (Fig. 3.) 
Physiology. — Apply to the care of hens and cows and other animals 
the principles learned in physiology concerning winter exercises, 
ventilation, exposure, etc. Show that undue protection renders any 
animal less resistant and when ventilation is limited at the same time

Practical and field exercises. — Continue the work in milk testing and 
corn judging until some skill is attained. Those who are to hatch

them ample room and suitable food. The testing of eggs and care 
of the market eggs are important from now on. (See Farmers' Bui. 
562.) Each pupil should decide on what club work or home projects 
he is to take up during the coming season.
