the water, apparently with great enjoyment; for roots 
not only seem to seek the water, but to like it, and to 
flourish in it. 
If you break off at the ground one of your bean 
plants, and place the slip in a glass of water, you will 
see for yourselves how readily it sends out new roots. 
I have read of a village tree the roots of which had 
made their way into a water pipe. Here they grew 
so abundantly that soon the pipe was entirely choked. 
This rapid, luxuriant growth was supposed to have been 
caused by the water within the pipe. 
So you see there are underground roots and above- 
ground roots and water roots. Usually, as you know, 
the underground roots get their food from the earth; 
but sometimes, as with the Indian pipe, they feed on 
dead plants, and sometimes, as with the yellow false 
foxglove, on other living roots. 
WHAT FEW.CHILDREN KNOW 
O-DAY we must take another look at the plants 
in the schoolroom garden. 
By this time some of them have grown quite tall. 
Others are just appearing above the earth. 
Here is a young morning-glory (Fig. 120). We see 
that its stem, like that of the bean, was the first thing 
to come out of the seed. This stem has turned down- 
ward into the earth. From its lower end grows the 
root, which buries itself deeper and deeper.
