We listened and heard, somewhere in the air about us, an extraordinarily musical hum—like a bee, but not just one note. This hum rose and fell, up and down—almost like some one singing. “No other insect but the Jabizri beetle hums like that,” said the Doctor. “I wonder where he is—quite near, by the sound—flying among the trees probably. Oh, if I only had my butterfly-net! Why didn’t I think to strap that around my waist too. Confound the storm: I may miss the chance of a lifetime now of getting the rarest beetle in the world—Oh look! There he goes!” A huge beetle, easily three inches long I should say, suddenly flew by our noses. The Doctor got frightfully excited. He took off his hat to use as a net, swooped at the beetle and caught it. He nearly fell down a precipice on to the rocks below in his wild hurry, but that didn’t bother him in the least. He knelt down, chortling, upon the ground with the Jabizri safe under his hat. From his pocket he brought out a glass-topped box, and into this he very skilfully made the beetle walk from under the rim of the hat. Then he rose up, happy as a child, to examine his new treasure through the glass lid. It certainly was a most beautiful insect. It was pale blue underneath; but its back was glossy black with huge red spots on it. “There isn’t an entymologist in the whole world who wouldn’t give all he has to be in my shoes to-day,” said the Doctor—“Hulloa! This Jabizri’s got something on his leg—Doesn’t look like mud. I wonder what it is.” He took the beetle carefully out of the box and held it by its back in his fingers, where it waved its six legs slowly in the air. We all crowded about him peering at it. Rolled around the middle section of its right foreleg was something that looked like a thin dried leaf. It was bound on very neatly with strong spider-web. It was marvelous to see how John Dolittle with his fat heavy fingers undid that cobweb cord and unrolled the leaf, whole, without tearing it or hurting the precious beetle. The Jabizri he put back into the box. Then he spread the leaf out flat and examined it. You can imagine our surprise when we found that the inside of the leaf was covered with signs and pictures, drawn so tiny that you almost needed a magnifying-glass to tell what they were. Some of the signs we couldn’t make out at all; but nearly all of the pictures were quite plain, figures of men and mountains mostly. The whole was done in a curious sort of brown ink. For several moments there was a dead silence while we all stared at the leaf, fascinated and mystified. “I think this is written in blood,” said the Doctor at last. “It turns that color when it’s dry. Somebody pricked his finger to make these pictures. It’s an old dodge when you’re short of ink—but highly unsanitary—What an extraordinary thing to find tied to a beetle’s leg! I wish I could talk beetle language, and find out where the Jabizri got it from.”
