"These negroes are worth from five hundred to a thousand dollars apiece if you want to sell them, and not many of them would be left if I should set them to digging in the open," replied Levi, laughing at his own argument. "Those ruffians could pick them off at their leisure, and we might as well not have any artillery if the cannoneers are to be shot down as fast as they show themselves. I will warrant that fellow in command on the other side has picked out his best riflemen for duty in the grove." "The negroes are not for sale," replied the planter. "I should as soon think of selling one of my sons as one of them. But the boathouse is between you and the enemy, Levi." "How long do you think it will take me with the force at hand to move the boathouse out of the way, Major Lyon?" demanded the overseer with a very broad smile. "I indorse Mr. Bedford's work," added Captain Gordon, who had turned to observe the operation of the enemy at the cross roads. "They are not making a good job of their work." As soon as the recruits had been ordered to the trees, and before the detachment sent to the grove had obtained their positions, Deck and Artie had obeyed the commander's order in hot haste. They had chosen a couple of trees on the very verge of the quagmire which lay between the lawn and the road to the south; and when the ruffians attempted to move the mules, both of them opened fire upon the animals. Both of the boys were good shots, and they hit the mark every time. The mule, though one of the most useful beasts in the world, is very uncertain at times. The testimony of soldiers is to the effect that mules object to being under fire. The two boys were near enough to each other to talk together, and they had agreed to fire into different teams, and they had wounded one in each of them. The two that had been hit not only made a disturbance, braying furiously, but they communicated the scare to the others. The mule drivers could do nothing with them, and in a minute or two the whole of them were all snarled up, and the men were obliged to unhitch them from the wagons and lead them away. The animals were so terrified that they bolted up the new road in spite of the drivers, and turned in at the bridge, which seemed to promise them a place of security, just as Colonel Belthorpe and his party galloped up to it. The mules were permitted to take the lead. Major Gadbury and Tom were with the planter of Lyndhall. Major Lyon saw them, and, by a roundabout course, joined them in season to prevent them from coming within range of the sharpshooters in the grove. It did not take the planter of Riverlawn long to explain the situation; and he was informed that twenty Lyndhall negroes, under the lead of Uncle David, in wagons, were on their way to the seat of danger. The horses were left in charge of the servants, and the party made their way to the fort, where they armed themselves with breech-loaders, and took places behind the trees with the recruits.
