River, lake and land conservancy in portions of the provinces of Anhui and Kiangsu, north of the Yangtsze River; . o the coast is one vast alluvial plainin the making and not yet finished. Thk Dip oi? Ti-ii?, Alluvial Plain The dip of this plain is as a whole to the southeast, but anexamination of the Map will show that the rivers flow in all directionsexcept west. Clim.\TE The climate is of a mild and temperate character, the thermometerranging from a maximum of 100° Fah. to a minimum of 20° winter is short; the ground freezes to a depth of from two to three inches, and none of the rivers or lakes become coveredwith ice. The soil is a light alluvial and of great richness, with theexception of some fifteen miles along the sea coast, where theelevation is not as 3et sufficient to free it from salt. Rainfall The rainy season is during June, July and August. Some rainsoccur during April and are of much benefit to the crops. Therainfall is ample, and when the rivers have been properly cleanedand regulated and provided with outlets, all ordinary floods willbe eliminated. ?•^^^^e^mi^i^-^^^. DYKE REPAIRING ON THE GRAND CANAL It is impossible to ascertain the average number of inches pernormal year, as no records have been kept, but the Chinese recordsshow that years of drought are almost unknown. At times local rains of great magnitude occur within the faminearea. In June, 1910, there was a local downpour in the region ofSze-chow, Ling-pi and Nan-Suchow, lasting some forty-two hours,during which it was estimated by the Divisional Engineer of theTientsin-Pukow Railway that twenty-four inches of water fell. No cleaning of rivers or opening of outlets will prevent muchdamage being done by such a rainfall as this. The mere force of thefalling water will pound any standing crop flat to the ground andmake it a dead loss. But whereas now the condition of the rivers,drainage canals, etc., is such that even a moderate amount of rainwater cannot run away, but stands week
