The second Euergetes and his successor Ptolemy Ptolemies Lathyrus (118-115 B.C.) furnished Eudoxus with a fleet to explore the Arabian sea.
The north-eastern portion of this range is of great altitude, and separates the headwaters of the Oxus, which run off to the Aral Sea, from those of the Indus and its Kabul tributary, which, uniting below Peshawar, are thence discharged southward into the Arabian Sea.
Now they form an official province of British Baluchistan within the Baluchistan Agency; and the agency extends from the Gomal to the Arabian Sea and the Persian frontier.
Thus the south-west monsoon begins in the Arabian Sea with west and north-westerly winds,which draw round as the year advances to south-west and fall back again in the autumn by northwest to north.
This large tract, extending from the Arabian Sea on the west to the Satpura mountains in the north, comprises a good part of western and central India, including the modern provinces of the Konkan, Khandesh, Berar, the British Deccan, part of Nagpur, and about half the nizam's Deccan.
