IN my attic at home there is a toy trunk, covered with cowhide - a little old trunk that my grandfather made for my mother when she was a little girl. And in this little old trunk there is a purse completely covered with bright Indian beads. It is made of a plain cotton material, and very well made too, and was bought from an Indian as a present for my mother about three-quarters of a century ago.

These keepsakes have always been very dear to me but just now they have an entirely new meaning. I expect to prove something by them.

A photographer has written me that he has been told that Portrait Film negatives will deteriorate and lose their good printing quality in about a couple of years because film base is absorbent. Also that glass plate negatives will not lose their quality because glass is not absorbent.

Of course we all know that gelatine is very absorbent but the gelatine can have nothing to do with it as both plates and films are coated with gelatine. And there is nothing for the film base to absorb but the gelatine and silver and atmosphere.

We know that film base hasn't absorbed anything in thirty years for we have perfect film negatives that old. But we really ought to go back before the time of film base and the only way to do that is to see what action cotton has had on silver because film base is made from cotton.

I know there is an old silver coin in that old purse so when I go home tonight I am going to see if the cotton material has absorbed that silver coin.

If I find that it has. I don't know that I will even trust glass again. I think I will go back to tin types for I saw an old tin type of myself the other day, made when I was a child, and the silver image was all there as good as ever.

When you influence the customer in her choice of proofs, compliment her on her good judgment.

The Eastman Safelight Lamp

THE printing-room or dark-room light should, above all things, be safe and be convenient, and these two requirements are combined with a wide range of usefulness in the new Eastman Safelight Lamp.

As will be seen by the illustration the lamp may be attached to a drop cord as it is fitted with a plug that will screw into any ordinary electric socket.

In the printing or enlarging room it is especially convenient, as a lamp is needed that will throw its light into the developing or fixing trays. The side light is more suitable for viewing negatives that are being developed, but even for this purpose the new lamp may be made to answer as it may readily be screwed into a wall socket.

As its more general usefulness is in the printing-room, however, it is regularly equipped with a Series 00 Wratten Safelight. This fits into a groove in the bottom of the metal body, the open end of the groove being closed with a light-tight metal door after the Safelight has been inserted.

The inside of the lamp body has high reflecting surfaces insuring the greatest amount of light that can be used with safety.

The Eastman Safelight Lamp differs from Wratten Safelight Lamps in that the light is direct.

For this reason a Mazda bulb of from 10 to 15 watts should be used. With the Series 00 Safelight the light is perfectly safe for all ordinary developing-out papers.

The Series 0 Safelight should be used for fast developing-out or bromide papers, or lantern slide plates; the Series 1 for ordinary plates or films, Series 3 for panchromatic plates or films.

The 5x7 Wratten Safelights are interchangeable and are furnished in any series at 75 cents each. Unless otherwise specified, however, the Series 00 is furnished with the lamp.

There are a great many uses for this handy little lamp, in the printing-room, the bromide-room, over dark-room sinks or fixing tanks, in the amateur finishing dark-room, or for general darkroom illumination. The price is $3.00 - at your dealer's.
