"I will tell you, my dears. I knew that the Indians of the pampas were horse Indians, and the idea struck me that as they could never have seen rockets, they would be horribly scared at night by them. rockets, you know, are used in war; and even if the riders are not frightened, it is quite certain that the horses would be horribly alarmed by one or two of these rushing fiery things charging into their midst. I therefore had them specially made for me by a pyrotechnist in London. One dozen, as you see, are ordinary rockets of the largest size; they contain colored balls, which will give out a most brilliant light. One of them thrown into the air, even where we believe any Indians to be, will light up the plain, and give us a fair view of them. The other three dozen are loaded with crackers. As you see, I have had a strong case of tin placed over the ordinary case; and one of them striking a man will certainly knock him off his horse, and probably kill him. The roar, the rush, the train of fire, and finally the explosion and the volley of crackers in their midst would be enough to frighten their horses altogether beyond control. What do you think of my idea?"
"Capital, capital!" they all cried.
"But how, papa," Hubert asked, "will you manage to make your rockets go straight at the Indians? All rockets I ever saw went straight up into the air."
"Yes, Hubert, because they were pointed up. A rocket goes whichever way it is pointed. Rockets in war are fired through a tube, or from a trough. We will use the trough. Set to at once, boys, and make a trough about four feet long, without ends. It must stand on legs high enough to raise it above the level of the wall round the top of the tower. Let there be two legs on the front end, and one leg behind; and this leg behind must have a hinge, so that, when it stands upright, it will be six or eight inches higher than the front, in case we want to fire at anything close at hand. When we want to elevate the head of the rocket to fire at anything at a distance, we pull the hind leg back, so that that end is lower than the front. Put a spike at the end of the leg, to let it have a firm hold on the floor."
Charley thought a moment, and then said: "I think, papa, it would be firmer, and more easily managed, if we made two legs behind, with another one sliding up and down between them, and with holes in it so that it can be pegged up and down as we like."
"That would be certainly better, Charley. Put your idea down upon paper, and let me see exactly what you mean before you begin."
Charley did so, and Mr. Hardy pronounced it to be excellent; and by night the trough was finished, and placed in position at the top of the lookout.
Mr. Hardy, in the course of the evening, explained to his wife that it was possible the Indians might venture to make a dash to carry off some of the cattle, and that, therefore, he had ordered the girls to be on the lookout, and to adopt every precaution upon moving out. To them he made an addition to his former instructions, namely, that not only should they look out before leaving the enclosure, but that, if one went out, the other should go up to the top of the tower every quarter of an hour to see that everything was still clear, and that if both were out, Sarah should do the same. The boys needed no instructions to load their revolving carbines, and the pistols and a double-barreled gun were handed over both to Lopez and Terence, with instructions to carry them always with them. Lopez required no orders on this score. He knew what Indians were, and had a perfect horror of them. Their friends at Canterbury were also put upon their guard, as their estates were also very much exposed. Three days passed over, and then the light iron plates arrived for the door and window shutters. Before they were nailed on large holes were cut in them for firing through, corresponding slits being cut in the woodwork. When they were fastened in their places all felt that Mount Pleasant could defy any number of assailants.
Orders were given to Terence that in case of the dogs giving the alarm at night, the occupants of the hut were to retire at once to the house; to which he replied characteristically:
"Sure, your honor, I suppose I may stop for a bit and pepper the blackguards till they get close to me."
