Instantly the well-known hiss resulted and a dense cloud of pungent smoke arose with such a quickness that I stumbled backward from the place, involuntarily. Only Fatty and one or two others of the Links beheld this exhibition, the others being already asleep. The fright depicted on the faces of this small but select audience was a wonderful thing to see. I determined at once to set about burning a quantity of charcoal, for already I had conceived an idea that it might be possible to utilise the explosive to advantage, and I intended at least to give my scheme a trial.
On the day that followed, the first thing I did was to have the Links collect a lot of wood, the softest and driest I could find. This I heaped up in a conical pile and walled in snugly with turf and a little of the clay, which was everywhere about us. When it was lighted and smoking slightly through various small chinks, I banked it up around the bottom and returned to the work on the flints.
Before we got through with those pebbles we had rough but serviceable arrow-heads by the hundreds, knives in plenty, hatchets for all, with some to spare, and sixty or eighty spear-heads, which were bound to long, stout hafts, in the regular course of finishing up. I reserved for my own personal arsenal two axes, two knives and fifty of the finest arrows in the lot. Also I assumed a general command, as custodian, over all the weapons and utensils in the tribe’s possession.
No sooner were the armaments complete than I went to my powder-making with indefatigable vigour, thankful for every day that passed without bringing the foe, which I dreaded and thoroughly expected to see come swarming up the slope from the woods. I made my fellows pound up charcoal till some were nearly as black as the enemy for whom we were preparing. The powdered stuff we placed in the baskets, several of which I plastered inside with clay, which dried hard and firm. The saltpetre, which we dug and brought up the hill, was treated in a similar manner, as was also the sulphur. Anyone to have seen me directing this business would have thought I intended to supply an old-fashioned navy with explosives.
During these days I in nowise neglected the archery practice, which alone could make my warriors capable of using the weapons to advantage. We shot at a target the size of a man, which I fashioned out of skins and heavy palm leaves. This being backed by a sort of hedge, constructed of bamboo and more of the leaves, we lost but few of the arrows employed. And the arrows used were not from our pointed stock, though they were whittled sharp on the end, so that many pierced the target as neatly as a bullet. Thirty of my force grew decidedly efficient, being accurate, strong shots who could be relied upon to perform good work on any attacking party. We also used the spears, in the throwing of which the Links took great delight. I was sure that come what might, the fellows would never again be so primitive as they were when first I met them in the jungle. Whether I left them or not, they would hereafter possess weapons which would place them far above the Blacks in point of capacity to kill.
One of the greatest difficulties with which I had to contend, while making my powder, was the frequent coming of rain. This threatened to make it all too wet to be of any use. There were also many days when a thick, damp fog rolled upward from the lower levels, slowly evolving into a ponderous cloud which covered all the jungle-world. The baskets containing the pulverized materials were doubly protected, however, by skins, and the roofs of the special dug-outs which we made, but the roofs were never entirely water-tight.
Being unacquainted with the recognised formulæ for mixing various powders, I simply took about three parts charcoal to one each of nitre and sulphur, and set the Links to grinding these substances together, slightly dampening the whole as before. The grayish stuff, which I regarded finally as the best product of which we were capable, I stored away, next to my own shelter. There must have been two hundred pounds of this powder, the making of all of which had only occupied us for a short time, after the several ingredients in their rough state had been assembled.
In order to impress the tribe with the urgent necessity of keeping all fire away from the baskets, I dropped a glowing coal into a handful as it lay on a rock. The vivid flash did so much to accomplish my purpose that I could hardly get the Links to approach the dangerous mixture under any circumstances whatsoever.
My next step now was to visit the swamp where the thicket of bamboo flourished. In this place, as I had expected, there were all sizes of this peculiar tree-reed, but the largest ones appealed to me most strongly. I carried off what I thought I should need, and selecting the driest of my stock, cut off a large section behind the joint, on one end, and in front of the next joint on the other. The piece then resembled quite a cannon, without further ado.
This thing I was aware was much too brittle to stand an explosion, but I meant to try it, nevertheless. To begin with I bored a vent through the hard, thick shell, near the end that was naturally plugged. Then I reinforced that plug by lashing a stone across the end firmly. Next I split some more bamboo and laid the strips lengthwise along the barrel, thus doubling the thickness, after which I had the whole thing stoutly wound about with tough, slender creepers, till I was sure it would resist a powerful tendency to burst.
