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 i 
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 peer ul screen for unsightly i 
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 filing in with soil to é 
the depth that the plants stood in the nursery. e 
Practical work.—The work provided for in the foregoing directions — 
f 
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. { 
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 girdiers puncture and lay eggs in small twigs _ 
and then girdle the twig so that it breaks off and fails to the ground. 
Have pupils look for twigs of hickory or pecan trees lyig on the © 
ground or hanging on the trees. Note how they have been cut off. 4 
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 lymg 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 numbe
