tribe, in India. The inhabitants of Britain were Iberians, a non- 

 Aryan race and related to some of the hill tribes of India. The hills 

 were peopled first because they were free from trees, and the soil was

 with timber, which they had no means of removing except by fire. The 

 forests were held to be more or less sacred, even at so late a period as

 Two Aryan races, the Celts and the Saxons, invaded Britain, one before

 ture from the race they overcame. At this time the community gen- 

 erally owned the land, and its management was vested in officials 

 elected for the purpose. The Romans introduced individual owner- 

 ship, and this was never uprooted. It grew gradually under the 

 Saxons and more quickly under the Normans, but made its most rapid 

 progress during the fifteenth and sixteenth centuries, when wool was 

 the valuable product and land was wanted for grazing sheep. During 

 this time the customary method was to cultivate a piece of land for a 

 few years and then, leaving it to go back to grass, break up another 

 piece, and cultivate it until it became unprofitable. It is interesting 

 to note that wherever population is scanty this method is adopted, 

 whether in the ages of antiquity in Europe or during the nineteenth 

 century in America. In some parts of the United Kingdom, modifi- 

 cations of this system existed at a comparatively recent date- The
