But this tower—one of the old style built before the modern tanks came into use—was not freshly painted. It had been allowed to fall into a state of disrepair. Some of the rungs were missing from the ladder that led up the side, and the tower itself had a forlorn and weather-beaten aspect, as though it had been deserted. This, indeed, was the case. The new tower tank closer to the station had been erected to replace it, and although the old structure had not been torn down, it was not now used.
