ing expert, and he had a business proposition
which he wanted to place before me.

"He told me he and four others had just returned to Auckland after
putting in six weeks among the volcanic beaches of the North Island,
searching--'fossicking,' he called it--for fine gold. These black sand
volcanic beaches are common in parts of New Zealand. The black sand is
derived from the crystals of magnetic iron, and there is frequently a
fair amount of fine gold mingled with them. By the continued action of
the surf the heavier materials, gold, and ironstone sand, are mingled
together between high and low water mark, and what appears as a stratum
of black sand is found on the surface or buried under the ordinary sand.
The gold is usually very fine, and the trouble of sifting and collecting
it is great. A man works for wages, and hard-earned wages at that, who
goes in for this kind of mining. But your true miner is ever an
adventurer and a gambler, and gold thus won is dearer to his heart than
gold which might be earned with less effort and more regularity in the
form of sovereigns. You see, there is always the chance of a big find.

"Moynglass and his party had met with fair success along the beaches,
but they wanted more than that. Moynglass was anxious to trace the fine
gold to its source, and find a fortune. He believed, like most miners,
that this fine gold is carried along the beds of the larger rivers and
distributed by the action of the sea along the different beaches where
it is found. His theory was that if the drift of the gold sands could be
traced to their source, a great quartz reef would be found which would
make the discoverers wealthy men. But he and his mates knew nothing
about geology, and they wanted somebody to go with them who could chart
the course, and lead them to the launching point of the gold.

"I had heard this theory before, and was not impressed by it. I should
probably have turned down Moynglass's proposition if, in the course of
his conversation, he had not produced a sample of ruby quartz from his
pocket and showed it to me. He said he had found it while exploring one
of the rivers of the Urewera country. I examined the quartz attentively.
It was emery rock, and imbedded in the pale green mass were ruby
crystals, and true Oriental rubies at that. I realized the valuable
nature of the discovery, and questioned the man closely as to where he
had obtained the ruby rock, but he became instantly suspic
