Cuba in War Time by Richard Harding Davis

This is an account of a voyage of discovery along the Spanish trocha, the one at the eastern end of Cuba. It is the longer of the two, and stretches from coast to coast at the narrowest part of that half of the island, from Jucaro on the south to Moron on the north.

Before I came to Cuba this time I had read in our newspapers about the Spanish trocha without knowing just what a trocha was. I imagined it to be a rampart of earth and fallen trees, topped with barbed wire; a Rubicon that no one was allowed to pass, but which the insurgents apparently crossed at will with the ease of little girls leaping over a flying skipping rope. In reality it seems to be a much more important piece of engineering than is generally supposed, and one which, when completed, may prove an absolute barrier to the progress of large bodies of troops unless they are supplied with artillery.
