54 BULLETIN" 305, U. S. DEPARTMENT OP AGRICULTURE. 



Have the pupils collect the following information at their homes 

 and report to the class: 



(1) What fruit trees are being sprayed this month? 



(2) For what purpose are they sprayed? 



(3) What sprays are used? 



Record these facts in notebooks. 



Practical exercises. — Preparing tables and collecting the facts 

 called for in the foregoing lessons supply ample work for the pupils 

 while out of the class. 



Correlations. — Language: Tabulate the facts with reference to 

 trees and write up the observations in connection with spraying. 



List new words and learn to spell them. 



Drawing: Make drawings of leaves and flowers that appear this 

 month. 



Geography: Note the locations of plants that are earliest in put- 

 ting forth blooms and leaves. Are they on hilltops or in low places ? 

 On the south side or the north side of hill or mountain ? Give reasons. 



Continued work. — Continue the studies with the special group of 

 birds. Note the coming and going of members of the group, their 

 method of securing food, the places frequented, and whether they 

 are found in flocks or alone. 



What members of the special group of mammals are putting in 

 their appearance? What are they eating? Are they providing 

 summer homes ? Where ? What kind ? 



Assigned work. — The chief reason for studying the mosquito in the 

 South is that one kind (genus) is the means of transmitting malaria. 

 This is quite a common disease and does much to incapacitate south- 

 ern people for efficient work. The idea that malaria originates in 

 swampy or marshy places is entirely erroneous. The disease is trans- 

 mitted solely through the anopheles mosquito. In most cases the 

 disease may be controlled by the use of quinine under the direction 

 of a physician, but the best method is to control or destroy the 

 mosquitoes. 



Have the pupils make a study of mosquitoes, at the same time 

 emphasize the importance of keeping the home premises free from 

 them. These pestiferous insects soon begin to put in their appear- 

 ance if preventive measures are not taken. Instruct the pupils to 

 rid their premises of all discarded tin cans, jars, buckets, and the 

 like, drain pools of water, and fill wells that are no longer in use. 

 Those places that cannot.be drained should have their surfaces cov- 

 ered with oil. Let the following outline serve as a guide in the study 

 of the mosquito:
