should be thoroughly prepared and well fertilized. Vegetables with 

 small seed should be planted on a ridge or bed. 



Assigned work. — With the assistance and direction of the teacher 

 pupils of this grade should set plants for a permanent screen. The 

 help of older pupils should be secured, but let it be the enterprise of 

 this class. The snowball makes a beautiful screen for unsightly- 

 places. If the school grounds are not inclosed, secure California 

 privet plants and set them this month. Make a ditch around the 

 school grounds 10 to 12 inches deep and 12 inches wide. Fill the 

 ditch half full of a mixture of manure and soil. Set the plants in 

 single or double rows 12 inches apart. Finish filling in with soil to 

 the depth that the plants stood in the nursery. 



Practical work. — The work provided for in the foregoing directions 

 should be done either after school hours or on the weekly holiday. 

 If it is desired to set a privet hedge, one or more of the patrons 

 should be invited to contribute the manure and haul it to the school 

 yard. If the school yard is quite large, one of the patrons should 

 bring a turn plow along with which to make the excavation for the 

 plants. The pupils of this grade should be required to take notes 

 on the several steps in the planting process. 



Correlation. — Language: Develop the foregoing notes and copy 

 them in the class book. 



Drawing: Make a sketch of a privet plant showing roots, stem, and 

 branches. 



Arithmetic: Develop problems as to the number of privet plants 

 required to make a hedge around the school yard ; also as to the cost 

 of the plants. 



ANIMALS. ' 



Continued work. — The study of birds and wild mammals should 

 be kept up as suggested in January. What is "ground-hog day" ?. 

 Continue collecting and studying cocoons. Store them for observa- 

 tion and study. 



Assigned work. — Twig girdlers puncture and lay eggs in small twigs 

 and then girdle the twig so that it breaks off and falls to the ground. 

 Have pupils look for twigs of hickory or pecan trees lying on the 

 ground or hanging on the trees. Note how they have been cut off. 

 Examine the twigs close to the buds to find small punctures. Cut 

 away the bark and determine whether there is an egg or grub present. 

 All twigs lying on the ground or hanging on the trees should be 

 removed and burned during the winter. 



Look under the bark of dead or dying pine trees for pine weevils, 

 bark-beetles, and sawyers. 



Practical work. — Studying and making notes on birds and mammals, 

 and looking for cocoons and twigs provide outdoor work. A number
