THE PLANT BODY

many similar shoots from the 

 base are called shrubs, as lilac, 

 rose, elder, osier(Fig. 13). Low 

 and thick shrubs are bushes. 

 Plants that produce one main 

 trunk and a more or less elevated 

 head are trees (Fig. 14). All 

 shrubs and trees are perennial. 

 Every plant makes an effort 

 to propagate, or to perpetuate its 

 kind ; and, as far as we can 

 see, this is the end for which 

 the plant itself lives. The seed 

 or spore is the final product of 

 the plant.

Suggestions. — 8. The teacher may assign each pupil to one 

 plant in the school yard, or field, or in a pot, and ask him to bring 

 out the points in the lesson. 9. The teacher may put on the 

 board the names of many common plants and ask the pupils to 

 classify into annuals, pseud-annuals, plur-annuals (or climatic 

 annuals), biennials, perennials, herbaceous perennials, ligneous 

 perennials, herbs, bushes, trees. Every plant grown on the farm 

 should be so classified : wheat, oats, corn, buckwheat, timothy, 

 strawberry, raspberry, currant, tobacco, alfalfa, flax, crimson clover, 

 hops, covvpea, field bean, sweet potato, peanut, radish, sugar-cane, 

 barley, cabbage, and others. Name all the kinds of trees you
