of profitable excursions,, and some just a few of the things one 

 would look for, but this study of haunts must become more 

 precise if its real value is to be discovered. It is, for instance, of 

 much use to have vivid picturing of the difficulties of particular 

 situations and of the varied ways in which different animals 

 meet these. It is instructive to find the same characteristic 

 cropping up in entirely different kinds of animals in the same sort 

 of haunt. Thus, to take an easy example, we may picture a 

 boreal group, in some way adapted to arctic conditions, 

 by permanent or by seasonal whiteness ; the picture is soon 

 filled up by the polar bear, the Greenland falcon, the snowy owl, 

 the arctic fox, the variable hare, the Hudson Bay lemming, 

 and so on. It is often profitable to keep to one type of creature, 

 say birds or insects, and to contrast the different kinds that are 

 found on the shore, on the links, in the fields, in the woods, on 

 the moor, on the mountains, and so on. This may lead on to 

 the power of forming what one may call " impressionist pictures " 

 of the characteristic groups of animals which may be seen on 

 the tundra, the steppes, the desert, the forest, the mountains, 

 and so on. 



From this the survey may broaden out still more in an attempt 

 to form mental pictures of the characteristic faunas of the great 

 " zoological regions," corresponding more or less to the great 

 divisions of the globe. To attempt detailed pictures would be 

 out of place, but there seems no reason why school children 

 should not be able to people their maps with some of the charac- 

 teristic animals, just as they fill in some of the rivers and moun- 

 tains. In his great work on The Distribution of Animals, Alfred 

 Russel Wallace gives combined pictures of the characteristic 

 animals of different regions, and with present-day resources 

 these could be readily multiplied and vivified. The whole 

 study could be made as pleasant as a game, especially if the 

 mental pictures are built up from the dramatic sketches which 

 abound in the works of the naturalist travellers. 



Gradually it may be possible to take imaginary journeys, 

 e.g. from Britain to Japan, to see that widely separated countries 

 may have very similar faunas ; from Florida to the Bahamas, 

 from Australia to New Zealand, to see that more or less adjacent
