"No," answered Dick, looking up from the signal card he was studying, "I wrote it the following Monday and sent it to Dad, but never heard anything from it."

"We heard from your last report," said Henry. "That Spig was a wise hombre, right enough. The revenue officer found out all about him, but 'Mexican Pete' was too quick. He left for parts unknown that same day, and all the authorities in Porto Rico are on the lookout for him. He's a famous smuggler down in these regions and a regular bad man in the bargain. It's said he has served jail sentences in nearly every town from here to Vera Cruz. He's a Mexican by birth, a bad man by nature and a wanderer most of the time by necessity."

"That is all true, Hank, but it is not getting down this Morse code," replied Dick. "We've learned the semaphore, wigwag and Ardois, and I think we can give the signal boys on the bridge a run for their money; but I can't seem to get these sound signals. Guess my ear isn't attuned properly!"

"I don't see why you want to bother with it, anyway. You don't have to learn it."

"Never can tell when such knowledge will come in handy; besides, Hank, it helps pass the time when we've nothing else to do. It proved pretty useful last week when we were having that scouting drill ashore and by knocking two rocks together I was able to tell you to go to the left of that clump of bamboo. If you'd gone the other way the enemy would have captured you and your message, which would have meant the capture of our whole detachment."

"Yes, I'd forgotten that, Dick, and seeing that we both hope to be made privates some day the extra pay we will pull down as first class signalmen is not to be sneezed at. Well, here goes; see if you can get this!"

Thereupon Henry began a quick tap-tap with a pencil against the rim of the brass bugle he held on his knees.

For an hour the two boys practised at their self-appointed task, never using a spoken word in the meantime, but often smiling at each other over the messages they sent back and forth.

Richard Comstock was not wasting his time in the service. He had enlisted with one stated purpose in view, and all his work was to him a means to an end. Every new bit of knowledge acquired connected with his profession was just one more step in the ladder he meant to climb, until his hopes and ambitions were realized.

The friendship existing between Henry Cabell and himself was of great help to both boys. They often had their differences of opinion, but petty quarrels and bickerings never entered in their discussions. Both lads were high spirited, quick to take offense but as quick to acknowledge their errors in the light of reasoning. Day by day, Henry was losing his attitude of snobbishness. His association with Richard, who tried to find something worthy in every person with whom he came in contact and to see the bright side to every cloud, was the best thing which could have happened for the hot-headed Southerner.
