But experience soon convinced them that a new dwelling house was a necessity. The buildings which they occupied proved to be both unhealthy and unsuitable for the work they were undertaking. The unhealthiness arose partly from the location. The ground in that section of the city is low, and liable to be submerged in the rainy season. A sluggish little stream ran just in front of the place, passing through the wall by a low gate, and if this happened to be closed in a sudden freshet, the water sometimes rose within the houses. There was a floor at least in the main building, but it was laid upon scantlings about four inches thick, these being placed on the ground. The boards were not grooved, and as a consequence while making a tight enough floor in the damp season, in the dry it opened with cracks a quarter to half an inch wide. The walls were of stone, built without lime, and with an excess of mud mortar, and lined on the inside with sun-dried brick. The result of all this was that the dampness extended upward several feet above the floor, and by discoloration showed in the driest season where it had been. The floor could not be raised without necessitating a change in the doors and windows, and it was doubtful whether this could be made with safety to the house. It is no wonder that, under such conditions, Mrs. Mateer began to suffer seriously from the rheumatism that remained with her all the rest of her life. Added to the other discomforts, were the tricks played them by the ceiling. This consisted of cornstalks hung to the roof with strings, and covered on the lower side with paper pasted on. Occasionally a heavy rain brought this ceiling down on the heads of the occupants; and cracks were continually opening, thus rendering it almost impossible to keep warm in cold weather. An appeal was made to the Board for funds for a new dwelling. Happily the Civil War was about over, and the financial outlook was brightening; so in the course of a few months permission for the new house was granted, and an appropriation was made. The first thing to do was to obtain a suitable piece of ground on which to build. Mateer had in his own mind fixed on a plot adjoining the mission premises, and understood to be purchasable. Such transactions in China seldom move rapidly. He bided his time until the Chinese new year was close at hand, when everybody wants money; then, striking while the iron was hot, he bought the ground. Long before this consummation he was so confident that he would succeed that, foreseeing that he must be his own architect and superintendent, he wrote home to friends for specific information as to every detail of house-building. Nothing seems to have been overlooked. He even wanted to know just how the masons stand when at certain parts of their work.
