22 NATURE-STUDY REVIEW [14:1— Jan., 1918 



invariably find some resting, showing that, while only the toes are 

 used in walking, .the whole foot is used in sitting. 



In talking about limb structure, the kangaroo is most helpful. 

 When walking slowly, he uses the entire foot, his short arms aiding 

 in his leap frog like jump ; but in rapid running he steps on only 

 the toes, making an upright posture. 



The greatest delight of the Zoo is the babies whether completing 

 the circle in the cattle, cat, dog or monkey families. There have 

 been the young of many species, ranging from a day to a year old. 

 Two little tigers, deserted by their caged mother, were adopted by 

 a big boarhound, the mother of only ten in her own brood. We 

 were happy that one fought the fight for life and won. The care 

 and devotion, shown by most of the wild mothers, are beautiful to 

 see, and lasting impressions of the wonder of life cannot be erased. 



So we go home with a better understanding of and broader 

 sympathy for the wild life. Teasing is absolutely prohibited, and 

 the only offenders of the law had to be shut up, those beautiful 

 African cranes that followed the children about to pick at their toes. 



At three-thirty, the tired but happy children take the car, to 

 live the Zoo trip over again on the morrow, as they tell their 

 experiences to the classmates remaining at school.

While the snow comes drifting down spreading a blanket of 

 white over the bare brown earth, our footsteps are hushed, the very- 

 air is still, except when the wild wind blows. But why this warm 

 blanket and quiet? It is Mother Nature's sleeping time for many 

 of her children. 



It was not always thus. Away back in the dim past of our 

 world's life history, from the animals point of view, the world was a 

 much better place to live in. The climate was mild, the vegetation 

 luxuriant, there was always something to eat. 



The early, early rodent ancestors of our Chipmunks and Squirrels 

 had no need of a furry coat. But some day a slight chill came into 

 the air, and gradually oh ! so gradually, covering eons of time, that
