We were permitted to take up the receivers and listen to a faint scratching sound which must have come from a long way off.
Indeed the officer told us that it was a message from the enemy that we heard.
"Our men just picked it up," he explained; "we think it must come from a French wireless station across the river.

Naturally we cannot understand it, any more than they can understand our messages--they're all in code, you know.

Every day or two we change our code, and I presume they do too." Two of our party had unshipped their cameras by now, for the pass which we carried entitled us, among other important things, to commandeer that precious fluid, gasoline, whenever needed, and to take photographs; but we were asked to make no shapshots here.

We gathered that there were certain reasons not unconnected with secret military usage why we might not take away with us plates bearing pictures of the field wireless.

In the main, though, remarkably few restrictions were laid upon us that day.
