can be made perfectly safe by wearing a veil and a pair 

 of canvas gloves with -an extension to reach halfway 

 up the arms, as shown in Figure 170. An elastic band 

 placed above the top of each glove keeps the bees out. 



Most of the bees in this country are either the wild Races of 

 black bees or the golden-banded Italian bees. The 

 latter are considered by far the better, as they are less 

 liable to become diseased and &re also gentler than the 

 black bees. 



Experiments and Observations 



1. Collect eggs, larvae, pupae, and adults of as many insects 

 as you can. Watch the changes from one form to another. Feed 

 insects with the leaves on which they are found. 



2. Make an emulsion of kerosene and soap and water. Spray 

 it or wash it upon plants infested with scale insects or plant lice. 



3. Using a hand lens, or a better microscope, examine small 

 insects and insect eggs. 



4. Note all the differences you can between an earthworm 

 and the larvae of some insect. Watch the earthworm crawl.
