shoots them some distance at the start and also provides 
them with a sticky covering, so that they may have a 
chance to get carried still farther. 
Some plants have sticky hairs growing to their seed 
pods. We know that a good many plants have their 
pods covered with hairs which are hooked at the ends. 
Well, some are covered with hairs that have a drop of 
viscid substance at the tip, instead of a hook; these 
hairs fasten on quite as firmly as if they were hooked. 
The pretty little twin flower, or ground vine, as it is 
sometimes called, has a pair of scales growing about its 
seed pod, and these scales are covered with sticky hairs. 
The soft little mouse-ear chickweecl, that grows every- 
where in waste places, has several species which are 
covered all over with fine hairs which have a sticky tip. 
When the plant withers, it is easily pulled from the 
ground, and as it remains sticky, even after withering, 
the whole plant is often carried away by passing ani- 
mals or people, and its seeds 
shed in some distant place. C)C\ f \ \ 
See if you can find some 
plants that have their seeds ^ 
carried because some part of 
the plant is sticky. There 
are not a great many of 
them; still, if you look long 
enough, you will be sure to find some.
