The different methods of motherhood comport with the habits of Hfe and environment of the plants and vary as widely as those of hens and ducks. We have cold-loving plants, corresponding to the polar bear, and warmth-loving plants, corresponding to the monkey. We have the sedges that thrive in wet places, like the beaver; the cactus that is must comfortable when lo- cated in a desert, as are the lizards. There are social cliques among the plants as exclusive as are the people who live on the avenue. Each plant clings tenaciously to life and by its own pe- culiar method of motherhood propagates its family, and tries to exclude all rival. A boy's laboratory.

Other plants having aggressiveness leave no place for the plant of shiftless and half-hearted purpose. In the thrifty soil of my well tilled meadow there is no place for white daisies. Later, when the constitution of the grass becomes im- paired and its luxuriousness declines, leaving patches of bare soil, the daisy finds its opportunity to get a foothold. As the grass continues to decline, the population of the daisy increases. It is commonly said that the weeds " run out the grass," but such is a mistaken idea. When by reason of declining vitality the grass vacates the sod, the weeds come in as new tenants. If I invigorate my meadow by tillage and fertilizers the daisy will disappear and the grass be the sole possessor. Understand, please, that there is competition among different kinds of plants just as there is in the business world to secure trade. LESSON LXXXVI. Purpose.—To let the pupil see that one of the ways
