 in her faith that she can do so. Observe, 

 for instance, how she safeguards the trees. 

 First, she strips them of encumbering and 

 storm-holding foliage that which pros- 

 trates or snaps so many noble trees in sum- 

 mer hurricanes. Then she gradually stops 

 the flow of the sap, so that as the cold in- 

 creases the veins of the tree are drained, 

 and it presents no point of attack for frost. 

 At the same time the soft outer layer of 

 new wood, just underneath the bark, hard- 

 ens and forms, as it were, an inner coat of 

 mail, a cuirass, to stop the spear of the cold. 

 When you hear a tree crack in a sharp win-

 obstructed the complete draining of sap from 

 its veins, and a drop or two somewhere has 

 frozen and split the restraining fibers. 



But nature does not stop with the faith-

 tree. She makes armor and clothing for 

 its embryonic buds as well thick, hard,

 an inner lining of woolly down, like a
