3o6 Bird - Lore 



The southern part of the vast, boreal zone we are describmg contains the 

 Canadian fauna with two others of small extent, one, the Aleutian, the other, 

 the Sitkan, which you can easily locate along the northwestern part of the 

 Pacific coast. 



It would take too much space to mention all of the plants and animals 

 which find their most favored habitat in this zone. The lynx, marten and 

 porcupine are famiUar species, if not in the field at least in story and menagerie, 

 as well as the Canada Jay, White-throated Sparrow and Myrtle Warblers. 

 Wild berries grow here, such as huckleberries, blackberries and cranberries, 

 for this is the first zone, coming south from the north pole, in which agri- 

 culture may be engaged in successfully. The southern part of the Canadian 

 zone, it is needless to say, is by far the most favorable for such crops as white 

 potatoes, beets, hardy apples and cereals. 



Right here we may learn two facts, which you ha\'e doubtless already 

 guessed, first, that the farther one goes from the poles toward the equator, 

 the greater is the number of kinds of vegetation and animals found; and 

 second, that although in North America the land-areas become smaller and 

 smaller in extent tow^ards the tropics, there is far more diversity in the physio- 

 graphy of the United States, Mexico, the West Indies and Central America than 

 farther north in the zones we have been studying. Our next lesson will tell 

 something of the character of the birds' map from northern United States 

 southward.

SPELLING EXERCISE 



It is suggested thai after learning to spell the lists of words gi\'en below, 

 the derivation of each word be looked up, plural forms, wherever they occur, 

 be noted and that each pupil be assigned a word to investigate, to the end that 

 at least one interesting fact be reported in the classroom with reference to 

 the word in question, as well as its grammatical significance.
