Claude is listening in silence; but when Mrs. Angland speaks of his uncle’s mention of chemistry, he rises quickly, and, seizing the letter, holds it to the light, and then proceeds to carefully examine the remainder of the packet, including the cartridge case, etc. He is rewarded by finding the single word that heads this chapter scratched upon the tarnished brass of the latter. “Hidden,” he murmurs, for luckily he knew a little Greek. “Hidden, what is hidden?” and falls to poring over the letter once more.


CHAPTER III.
EUREKA.

“I had a vision when the night was late.”

UTSIDE on the verandah a happy couple are sitting enjoying the hay-scented night wind as it blows in gentle gusts up the valley. Dick and Mollie are in that delightfully idiotic frame of mind known to the vulgar as “being spooney.” A great silver moon is shining down, as only a New Zealand moon can shine, over the forest-clad Hunua ranges in the distance and the neighbouring dewy pastures, where white-backed cattle can be seen resting for the night. The weird-voiced weka calls from the dark fern-hill on the right, and a couple of night-jars, called “More Pork” by the colonists, from their peculiar cry, are proclaiming at intervals their carnivorous desires from the grand Puriri tree by the stockyard. The youth and his betrothed are thinking of anything but the letter that is engaging the attention of the people indoors, and Claude’s voice calling loudly upon Dick is by no means a welcome sound.

“Dick,” comes the summons again.

“Here I am,” answers the owner of the one-syllabled cognomen. A parting squeeze, and he opens the door, and walks into the room rubbing his eyes.

“Look here, Dick,” says his friend, without raising his head from its bowed position over the letter upon the table. “Here’s the summons I expected from the poor Doctor. But it’s an enigma, I’m certain. I’m bothered if I can get at its meaning. Read it, and find out its hidden signification, there’s a good fellow.”

Dick’s face is generally a smiling placid one, but it is curious to notice how it changes, and becomes thoughtful and determined, as its owner catches sight of Claude’s knitted brows and anxious, worried look.
