The turning lathe premium announced in the previous issue is quite as successful as we anticipated it would be, and many readers of this magazine will soon be the happy owners of these lathes. Those who have visited our office, and seen the one here on exhibition, have expressed the opinion that they do not see how we can offer such a fine lathe for such a small number of subscriptions. It certainly is a very liberal offer, and we are confident that every reader without a lathe would earnestly wish for one could they but see it. We will make this an easy matter in the following way; for the first one hundred lathes, we will receive subscriptions for one-half the specified number, the balance payable in cash at the rate of fifty cents for each subscription lacking the requisite number. Six subscriptions and three dollars would, under this arrangement, enable a subscriber to obtain the smaller lathe; and seven subsciptions and four dollars, the larger one. The little work required to get this number of subscriptions should make the lathe easily obtained by anyone. Try it.

As many of our readers are interested in electricity, we have arranged for a series of articles on "Electricity by Experiment," the first chapter to be published in the next issue. Not only will many interesting experiments be given, but complete descriptions of how to make the apparatus necessary to perform them. At the same time, care has been taken to keep the character of the experiments and the necessary apparatus, to as simple lines as the subject will admit. Anyone desiring to thoroughly study this important subject should become a regular reader of this magazine. Those soliciting subscriptions should call attention to this series of articles when talking with those likely to be interested in them.

A new gem, lilac-colored and transparent, has been found in two distinct places in California, the most plentiful deposit being only a short distance from the town of Palo, and within a mile of a well known rubellite mine. Dr. Baskerville gives it the name of Kunzite, in honor of its discoverer, Dr. Kunz, who has described its tint as as sort of "rosy lilac," varying from a very pale tinge when looked at traversely, to a rich amethystine hue when observed lengthwise. When cut and mounted in a certain way, one of these crystals yields a gem of unusual beauty. The discovery is of more than ordinary interest because nothing similar to the new gem has ever been seen by gem experts or jeweller's before. In the course of the tests by Dr. Baskerville, the Kun-site crystals were subjected to the action of ultra-violet light without showing any evidence of flourescence or phosphorescence, and it was not until it was subjected to the bombardment of X-rays of very high penetration that it became at all fluorescent. On its removal to a dark chamber, it exhibited a persistent white luminosity never before observed in its class of minerals.

A remarkable pearl cluster from Shark's Bay, West Australia, will be exhibited at the St. Louis Exhibition by C. A. Burt. It consists of about 150 pearls in a solid cluster, and measures several inches, and is about 1/2 inches thick. A cluster known as the Southern Cross, found some years ago at the Laceped Islands, was sold for close upon $50,000, and judging from this, the cluster should be worth from $75,000 to $100,000.
