THE first great advance that was made in the study of Geography was due to the spread of the Greek colonies along the shores of the Euxine and the advancedPby Mediterranean, commencing with the eighth century before the Christian era. By their means the horizon of knowledge was rapidly and continuously extended, enquiry was promoted into the natural features of the interior of the neighbouring continents and the condition of their inhabit- ants, and an impulse was given to speculation on larger questions connected with the formation and constituent elements of the Earth. This remarkable movement, a phenomenon causes of in early Greek history second only to that of the their Estab- . * . YT • 'JJL Hshment. creation of the Homeric poems, was due to more than one cause. In the first place, it provided an outlet for the superfluous population of the Greek cities, which about that time was increasing with extraordinary rapidity, and threatened to involve them in serious domestic perplexities. In other cases colonisation served as a remedy for political feuds and party
