Another burst of laughter greeted the discomfiture of the Pixie aide; after which Spite said: "We have called to see this patent spring net that Hyptiotes has invented. Where shall we find the fellow's laboratory? It is close by here we are told."
The party was directed to the adjoining tree, a low growth of pine, where they found the inventor awaiting them. He was already stationed upon his net, which he called from its shape the "Triangle," a name, by the way, that has been transferred to himself. It is in fact a triangular snare composed of four threads gradually widening at one end and at the other converging upon a single thread. The four threads are regularly crossed in the manner of the common orbweb, and indeed the whole snare resembles a section of four radii cut out of a round snare. The line upon which the threads converge is fastened to some fixed object and on this, back downward, Hyptiotes was placed.[AS]
When Spite's party arrived he left his position to greet them, and at once began to explain the spring net. His son was stationed on the trap line, and as he got into position I could see the whole snare rapidly tightening up until every cord was taut. "Now," said Hyptiotes, "observe that the operator holds that part of the trap line next the net within his hands. The part next the branch he holds with one foot. These two parts are drawn tight. Now see! between the lad's two feet there is a third portion of the line which is slack, and coiled up in a loose ball."
"Yes, yes," said Spite gruffly, "we all see that; but how does the machine work? That's what we want to know."
"Patience, Captain! I'm coming to that. Watch please! I will let this bit of leaf represent the insect, or a Brownie if you prefer. I shall throw it quickly against the net and do you note what follows."
As the scrap struck the cross lines, instantly the whole structure flew forward with a slight snap, then as suddenly was drawn taut, and again snapped loose. This was repeated several times. The leaf was caught by the sudden relaxing and shooting forward of the cross lines which by this motion were thrown around the leaf; the latter, after several springs of the net, was completely entangled and hung vibrating within the snare.

"There," cried Hyptiotes, "you see how well it works! Let me show you the principle. You have seen the coil of slack line between the two feet. Fix your eye now upon the foremost one. I will touch the net. See! instantly this claw releases its hold upon the line, and the whole net shoots forward as far as the coil will allow it. Follow closely, still, and you will see that the claws rapidly pull in and tighten up the trap line while the coil of slack line meanwhile again rolls up. That's the whole secret of my spring net." So saying, Hyptiotes put his front paws over his head, and stroked it forward with a self-satisfied air as though he, at least, had no doubt of the high merit of his trap.
Spite examined the structure carefully, made several more trials of its working, and then expressed his hearty approval. "Very good, indeed. I think it will be a valuable addition to our armory. Now, if we only had a few Brownies at hand for you to try it on, your demonstration would be quite perfect. By the way—" He clapped his hands together and laughed. "A capital idea that!"
