For covering garbage stacks perhaps the best vines are 
wild cucumber, Japanese hop, German Ivy and the Nasturtium. 
Show pictures. Make a list of the places on your home ground 
where you think vines are needed. We will see if our mothers 
and fathers will let us plant vines there. 
2. Lice on Poultry. 
I. Preparation. 
I am going to make a list on the blackboard, with your 
assistance, of all the common diseases or ailments of poultry. 
II. Presentation. 
The most common ailments of poultry are the parasitic 
diseases. These parasites are lice and mites, and the diseases 
they cause are the ailments which we are going to talk about 
in our lesson today. 
How can we tell that a fowl has body lice? (By examin¬ 
ation.) 
Where do you look on the body? (Look under the wings 
and on the skin about the feather roots, on the abdomen, back, 
neck and head. All fowls are lousy unless treated.) 
AVhat do your fathers and mothers use to keep the lice out 
of the chickens? (If they don’t find this successful, use pure, 
fresh, unadulterated, Persian insect powder. Dust it thor¬ 
oughly into the plumage and work well down to the skin and 
all over the body. • Repeat dusting in ten days. This should be 
effective for three months. Lice breed, on the fowl, in the 
plumage.) 
III. Comparison. 
How do the lice differ from mites? Mites are smaller and 
no not breed on the poultry but in the cracks and crevices about 
the house or under the accumulated droppings. Both are due 
to lack of cleanliness in poultry quarters, although lice appear 
if the poultry are not treated about every three months no 
matter how clean the quarters. For mites use a good liquid 
lice killer for painting roosts and dropping boards. 
IV. Generalization. 
All poultry should be kept in clean quarters and examined 
and treated for lice if healthy fowls are desired. Poultry as 
well as people thrive best under cleanly conditions. 
V. Application. 
Examine the poultry quarters in your home. Find out by 
examination if they are lousy. Ask your mother’s permission 
to treat them. Find out if lousy poultry lay as well as those 
that are clean.
