The seeds of the willow (Fig. 62) a on 
have silky white sails such as we have Ge = 
found already in the plants of the milk- 
weed and willow herb; and the cotton- 
wood tree is so called because its tufted 
eo. seeds remind one of the famous cotton 
it ones seeds from which we get our cotton thread 
et eas 
he (Cap roe 63). 
There are other trees which use wings 
instead of sails when they send their seeds 
flying through the air.

Here you have the winged fruits of the 
maple (Fig. 64). In summer you see these winged 
fruits hanging in clus- 
ters from the trees; and 
later in the year they 
are thickly scattered 
along the village street 
and in the city squares. 
You can understand Fic. 64 
how easily the maple seeds inside these cases would be 
carried upon the breeze by their wings.
