of three earlier delta arms of the Yangtse kiang, the southern entering the sea at Hangchow 120 miles further south, the third being the present stream. As we wound through this great delta plain toward Shanghai, the city of foreign concessions to all nationalities, the first striking feature was the “graves of the fathers”, of “the ancestors”. At first the numerous grass-covered hillocks dotting the plain seemed to be stacks of grain or straw; then came the query whether they might not be huge compost heaps awaiting distribution in the fields, but as the river brought us nearer to them we seemed to be moving through a land of ancient mound builders and Fig. 24 shows, in its upper section, their appearance as seen in the distance.
As the journey led on among the fields, so large were the mounds, often ten to twelve feet high and twenty or more feet at the base; so grass-covered and apparently neglected; so numerous and so irregularly scattered, without apparent regard for fields, that when we were told these were graves we could not give credence to the statement, but before the city was reached we saw places where, by the shifting of the channel, the river had cut into some of these mounds, exposing brick vaults, some so low as to be under water part of the time, and we wonder if the fact does not also record a slow subsidence of the delta plain under the ever increasing load of river silt.
A closer view of these graves in the same delta plain is given in the lower section of Fig. 24, where they are seen in the midst of fields and to occupy not only large areas of valuable land but to be much in the way of agricultural operations. A still closer view of other groups, with a farm village in the background, is shown in the middle section of the same illustration, and here it is better seen how large is the space occupied by them. On the right in the same view may be seen a line of six graves surmounting a common lower base which is a type of the larger and higher ones so suggestive of buildings seen in the horizon of the upper section.
