In a brief space the Brownie army had surrounded three sides of the fort; the fourth side faced the Lake, and was safe from approach of land troops. Then Captain Bruce sent out a number of scouts to view the Pixie works and report upon their strength and the best points for attack. Let us join the Captain and his staff, and listen to these scouts as one after another they return with their reports. We shall thus learn something of the Pixies' deft handicraft and cunning ways. [Illustration: FIG. 17.--The Bell Shaped Turret of Pixie Globosa, of the Wheel Legion.] "The first obstacle that I met," said Sightwell, who was the first scout to report, "was a line of barricades occupied by the Wheel Legion. This is formed of round webs woven upon grass and weeds, closely joined to one another and strung in a semicircular form along the whole front of the fort. Armed pickets are stationed at the open centrals of the snares. At either end of this crescent or demilune is a large orbweb, surmounted by a tower. One tower is wrought out of leaves lashed together by silken threads; the other is the bell shaped turret of Pixie Globosa.[K] [Illustration: FIG. 18.--Fort Spinder.] "The centre of the demilune is occupied by a company of the Tubeweaver Legion. They have built a broad, irregular pavilion above and around the surface foliage, whose margin is lashed by strong cords to grass stalks and other herbage. Near the middle is a long tubular entrance which opens out upon the top."[L] "Did you venture into it?" asked the Captain. [Illustration: THE BOY'S ILLUSTRATION. FIG. 19.--Fort Spinder as the Boy saw it.] "No! I climbed a tall weed to reconnoitre, and from the summit noticed that Pixies, whom I had seen to pass underneath the canvas, appeared again through a round hole in the roof and thence passed down into the camp. Then I descended, cautiously made my way through the grass, and came near enough to see the opening into the tube, which is really the southern or front gate to the encampment. It is set close to the ground and is well concealed. It is guarded on each side by a sentinel. From my weed-top observatory I could see that beyond the demilune, and between it and the fort, the main camp of the Pixies is pitched. The space is well covered with tents, and everything inside seems to be settled into homelike and comfortable condition." "Yes, yes!" exclaimed Bruce with an impatient gesture. "The wretches evidently intend to stay--if they can. But what else did you observe?" "Nothing important. I thought best to return with this news, while Glideaway, who went with me on the scout, went around the demilune to observe the front of Fort Spinder. He ought to be back ere long." True to his friend's prediction, Glideaway soon appeared, slipped quietly into the circle of officers, touched his Scotch bonnet and awaited leave to report. "Well," said Bruce, "what have you to tell?"
