to swell his ranks to a formidable host, and word was sent to the Greek capital, from Bulgarian and Greek sources, that the waters of the Black Sea were covered with the vessels of a Russian fleet. The Emperor did not hesitate what course to adopt, but hastily despatched an embassy to meet the invader with offers to pay the tribute exacted by Oleg and renew the treaty between the two countries. The Imperial messengers fell in with Igor at the mouth of the Danube, and their proposals were agreed to after a consultation between the Prince and his _droujhiniki_,[11] who in fact gained without further struggle as much as they could have hoped for in the event of a victory. Igor returned to Kiev as a conqueror, loaded with presents from Romanos, who sent thither in the following year his ambassadors with a text of the treaty. This was sworn to by the Prince and his captains before the idol of Peroun, except in the case of the Christian minority, who performed their oath at the altar of S. Elias. The fact of a Christian cathedral--a designation probably more ambitious than the building--being established at Kiev at this period speaks much for the toleration shown to the foreign religion by the followers of the national god. Igor did not long enjoy the fruits of this success. Baulked of their expected campaign, his men of war chafed at the inaction of the old man’s court, and envied the comparative advantages thrown in the way of Svenald’s body-guards. It was a custom of the Russian rulers to spend one-half of the year, from November till April, in visiting the scattered districts of their dominion, for the double purpose of keeping in touch with their widely-sundered subjects and gathering in the revenue. This winter harvesting of the tribute (which Igor in his declining years left in the hands of his deputed steward) is interesting as being probably the earliest stage of Russian home trade. For the most part the payment in kind consisted of furs and skins, the bulk of which went from the various places of collection in boat-loads down to Kiev, from thence eventually making its way to the sea marts of Southern Europe. The forest country of the Drevlians, rich in its yield of thick-coated sables and yellow-chested martens, lay in convenient neighbourhood to Kiev, and thither the Prince’s men clamoured to be led for the purpose of gleaning an increased tribute. In a moment of fatal weakness Igor consented, and in the autumn of 945 set out to close his reign as he had begun it, in a quarrel with “the tree people” over the matter of their taxing. The armed host which accompanied the Prince overawed the resentment bred by this stretching of the sovereign claims, but the apparent ease with which the imposts were gathered in tempted Igor to linger behind his returning main-guard for the purpose of exacting a further levy. The exasperated Drevlians, hearkening to the counsel of their chieftain, Mal, “to rise and slay
