The Capture of Riga.

The map reproduced on this page gives details which show where Russia’s weakness now lays. The capture of Riga opens a way to Pctrograd, which is

329 miles in a direct line. This town, the third seaport of Russia, has a population 47 per cent. German, and since the beginning of the war has been a centre of German intrigue. It was founded by the merchants of Bremen some 800 years ago. The dotted line shows the former front.

The requirements of the Local Government Board, London, and other authorities, in regard to ventilation, fix the minimum allowance of air space per occupant as follows: common lodginghouses occupied at night only, 800 cubic feet - ditto, day and night, 400 cubic feet; ditto, seamen, 400 cubic feet; ditto, in Belgium, 469 cubic feet; ditto in New York 600 cubic feet. The minimum allowance of sleeping space in common lodging-houses in London was raised by the L.G.C. regulations to 350 cubic feet. * # * * Dr. writes:—“How can we expect to ventilate a small room Suppose there are only two gas jets; yet, even so there are less than 100'cubic feet per head, and in order to keep the air reasonably pure it would have to be changed ten to thirty times an hour. How arc we to change it ten to thirty times an hour without causing a draught?” % # sfc A report of the Advisory Committee on Tiural Cottages, London, says:—“As a result of further investigation and particularly of further medical evievidence, we recommend that the minimum allowance of air-space in the bedrooms of five-apartment dwellings be fixed at 400 cubic feet per adult.” # # $ Dr. Whitelegge says:— “it is found experimentally that with ordinary appliances, and under the average atmospheric conditions of the climate of England, the air of a room cannot be changed more than about three times an hour without causing inconvenient draughts.” &
