Annamese refused to lend a hand, and the Chinese died like flies from the malarial conditions. For a time work was at a standstill, and in the end it had to be suspended during the summer months. The upper part, on the other hand, especially that section which runs through the Namti valley, tested to the utmost the skill of the French engineers. And the cost was correspondingly great. Even as it is, much of the embanking seems to be of a rather slight character, and quite unfit to stand the tremendous tropical downpours of the early summer months. After leaving China I learned that I had passed over the line just in time, for the rains set in very early in the summer of 1911, and for weeks traffic was fearfully interrupted by landslips and broken bridges.
