THE AMERICAN FOREST INDIAN TRIBES. 2OI 



Similar results followed experiments made by Mr. 

 Ballard of Bombay, to give the vine an artificial winter 

 there, by exposing the roots of vines to the sun during 

 the hot season. * The vine, however, as we know, is 

 a plant capable of enduring almost any amount of 

 heat, and so long as there is a dry season during 

 which its roots can be exposed to intense drought, 

 that seems to act upon it almost as effectually as if it 

 were exposed to frost the foliage falls and an arti- 

 ficial winter's rest is obtained, and thus it has been 

 found to do fairly well in some of the oases of the 

 Sahara, where these conditions are realized. 



The object of the digression is to establish the point 

 upon which we have insisted: namely, that the appar- 

 ently opposite phenomena of heat and cold often pro- 

 duce very similar effects ; and the results of the above 

 experiments furnish us with a striking illustration of 

 the fact, so that it will be unnecessary to dwell further 

 upon it at present. 



We have now passed in review all the leading 

 phenomena of the great forest region of the temperate 

 zone, and we shall endeavour to give a short account 

 of man as an inhabitant of the forest, principally in 

 connection with the red Indian tribes which formerly 

 had their home in the North American forests. 



Subsequent to the discovery of America the red 

 Indians of the eastern forest region were necessarily 

 the first tribes that came into intercourse with European 

 adventurers, and at the time when the early expedi- 

 tions were sent forth from England, France, and Spain, 

 these peoples were found existing in large numbers
