Hawaiian group. On some of these islands, particularly La- 

 nai and Kahoolawe, they have increased to such numbers as 

 to become a veritable pest, destroying grass and brush, and 

 greatly interfering with the growth of forests at higher alti- 

 tudes. The destruction of vegetation by goats on these islands 

 has led to the development of semi-desert conditions under 

 which wind erosion takes place to an enormous extent. At 

 frequent intervals goat drives are organized by hunters for 

 the purpose of exterminating these wild goats. Some of the 

 drives have resulted in the capture and destruction of thou- 

 sands of goats. 



In the Philippines, there are but few goats and these are 

 raised for their milk. The goat is an important domestic 

 animal in almost all parts of Africa. Throughout Egypt the 

 goat is raised for both milk and fleece. The Angora goat 

 thrives excellently well in Algeria. The dwarf goat occu/s in 

 the Sudan, and throughout Guinea, the Congo, Angola, and 

 East Africa the goat is a familiar domestic animal. The 

 goat is also an important animal in certain parts of Mexico 

 where it is raised both for milk and for fleece. In tropical 

 South America, the goat is of minor img^ortance, except in 

 Brazil. Experiments with milch goats in the Belgian Congo 

 have thus far been rather unsatisfactory. They do not appear 

 to become acclimatized readily or to endure the heat of that 

 country. 



CAMEL 



The dromedary, one-humped, or Arabian camel is referred 

 by zoologists to Camelus dromedarius and the Bactrian or 

 two-humped camel to C. bactrianus. The two forms, how- 

 ever, have repeatedly crossed and some authorities consider 

 them races of a single species. The camel will readily find 

 a living on brush, leaves, spiny salt bushes, and other coarse 

 plants of little use to other domestic animals. The camel does 

 not well endure a humid atmosphere but will endure excel-
