XOO FIftST L-ESSOJVS WITH PLANTS 



130, If one were to pull the water -weeds from 

 the drift on the margins of lakes and ponds in 

 late fall, he would find many of the strands with 

 large bud-like bodies at the ends (Figs. 100, 101). 

 These buds drop to the bottom of the pond, and 

 in spring vegetate and give rise to new plants. 



SUGGESTIONS. Horticulturists raise onions in four ways : by 

 sowing the seed; by planting bulblets (Fig. 97); by "multipliers," 

 which are bulbs that break up into several bulbs during the pro-

 posely arrested in their growth the previous year (by sowing seed 

 in dry ground and allowing the plants to stand very close together) 

 and which, when planted, complete their growth and become mer- 

 chantable bulbs. 



XX. HOW SOME PLANTS GET UP IN 

 THE WORLD 



-. The hop reaches light and air by coiling 

 around some support (Fig. 102). If the pupil 

 has access to a hop -field (hops often grow on old 

 fences) or to the Japanese hop of gardens, let him 

 observe the direction in which the stems twine. 

 He will find the tips coiling from his right to his 

 left, or in the direction of the sun's movement. 



132. The morning-glory (-Figr-103) twines in the 

 opposite direction, from the observer's left to 

 right. Fig. 104 is ^ morning-glory shoot which 

 was taken from its support, and the free end, 

 above the string, coiled about the stake in the
