Under his weak successor (Rolt, 1677-1682), the English waters, the value of which had now been proved, became the battle-ground between the rival navies, and for some years Bombay lay at the mercy of both.
From and after that time the British Admiralty and the navies of other countries began to give great attention to the development of electric wave telegraphy.
By the middle of 1905 a very large number of vessels had been equipped with the Marconi short distance and long distance wireless telegraph apparatus for intercommunication and reception of messages from power stations on both sides of the Atlantic, and the chief navies of the world had adopted the apparatus.
They traded also on the Red sea, and opened up regular traffic with India as well as with the ports of the south and west, so that it was natural for Solomon to employ the merchant navies of Tyre in his oversea trade.
They resulted too in a number of "chartered companies" - that is to say, the three military orders, which, beginning as charitable socities, developed into military clubs, and developed again from military clubs into chartered companies, possessed of banks, navies and considerable territories.
