fessional photographers, while the extension lenses are now listed for nearly all series of Cooke anastigmats.

On other pages one is told how to test lenses, and why people misunderstand the term depth of focus. They have also tried to state just how anastigmats differ from ordinary rectilinear lenses. A copy will be sent upon request.

We have received from the G. Cramer Dry Plate Company a copy of their latest booklet on "Isochromatic Photography," written especially for the general photographer. We call attention to the tabulated "Questions and Answers," beginning on page 12, as being of value to the individual who is uncertain as to which filter he needs, and its specific effect in action. These questions have been selected because of their frequent recurrence in regular correspondence, and are here compiled with the double idea of not only saving time in dictation, but as conveying a reply more complete than would be possible in personal correspondence.

The C. P. Goerz American Optical Company, report a very satisfactory and encouraging sale of their high-grade Anastigmats and Cameras. The volume of business handled by them this summer far exceeds that of the same period in the past few years and they look forward to a corresponding heavy demand for their goods during the coming fall and winter months.

Notwithstanding the increased volume of business the firm arranged that all of their employees receive the customary vacation with full pay, because the management felt that all the employees, the clerical as well as the factory staff, all who helped to a successful result, should have a chance for enjoyment and recreation.

Absolute safety surrounds your negatives in developing if you use the Eastman Plate Tank.

A record of a perfect print from every sheet in a gross is the claim of Cyko Paper.

The convenience of the Eastman Flash Sheet is well-known and the flash sheet holder increases that convenience to a much greater extent, the operator having full control of the light and can easily secure the desired angle. Can be held in the hand or attached to tripod. Acts as a reflector and so no light is lost by diffusion

As an example of the closer relations existing between employer and employees we call attention to the characteristic gift of Mr. J. J. Bausch, head of the wellknown manufacturers of lenses and optical instruments, The Bausch & Lomb Optical Co., on his passing the four-score mark, by contributing $10,000 to the fund established by the late Henry Bausch for the aid and relief of the company's employees. Also the gift of the employees to Mr. Bausch of a solid silver humidor, in the shape of the factory of 1865 in which the company was started.

Mr. Bausch is still active in the business and takes a lively interest in the enormous business of which he has been a part and which stands as a monument to his industry and energy.

THE EASTMAN FLASH

SHEET HOLDER.

Everybody who has made flashlight pictures will instantly appreciate the advantages of the Eastman Flash Sheet Holder.

The convenience of the Eastman Flash Sheet is well known, and the Flash Sheet Holder increases that convenience to a great extent. With it the operator has full control of the light and can easily secure just the desired angle of light, as the holder can be held in the hand in exactly the position wanted or may be attached to any standard thread tripod, if more desirable, by unscrewing the handle of the flash sheet holder and inserting in its place the tripod screw. In addition to this it also has a tendency to act as a reflector, and increases the light intensity in the proper direction. When the

THE NO. 1A SPEED

Designed for speed work, the IA Speed Kodak has fulfilled every promise, and we reproduce herewith two illustrations showing the remarkable work of this type of Kodak.

In illustration No. I we have a picture of the hurdler made from the view point pictorially correct-in other words, from the point at which the best composition and effect can be produced. The athlete coming towards the camera makes an interesting picture, but such pictures are possible with the ordinary type of shutters when used at their highest speed, provided the operator is expert enough to make the exposure at just the proper time-the time when motion is arrestedwhen the athlete is at the full height of his leap. At this point he remains poised in the air for a fraction of a second, and a creditable picture can sometimes be secured without a special speed equip

ment.

Illustration No. I might have been made under just such favorable conditions if the operator was fortunate enough to make the exposure at the proper time, and therefore does not prove that the negative was secured under the most difficult conditions.

In illustration No. 2 there is no element of doubt as to the speed of the hurdler as he has just started his leap and is pass

ing in front of the camera instead of coming towards it. This is a most severe test, and conclusively proves the remarkable speed of the No. 1A Speed Kodak.

Illustration No. 2 is not as interesting a picture from a pictorial standpoint as No. 1, and is shown to prove speedshown to prove to you that from whatever view point you make your picture, a sharp negative can be secured. No need to worry about a blurred image-no need to watch and wait for the period of arrested motion. You can make the negative when you wish from any point of view and produce a perfect negative with the IA Speed Kodak.

Another point in favor of this Kodak fully as valuable is in the making of slow snap shots. You may wish to make a

few negatives in the narrow streets of Chinatown-a few character studies showing the denizens in their natural surroundings. Sunlight is absent, and an ordinary snap shot would mean underexposure. With the IA Speed Kodak the shutter can be instantly adjusted for slow speed, thus making pictures that would, with ordinary shutters, be impossible. Chinatown is only used as an example of a condition that might exist anywhere. The picnic party in the shaded grove at lunch is another example, and there are many other poorly lighted subjects worthy of a photograph.

This instrument must be used to be fully appreciated. It makes pictures 21⁄2 x 44-a good proportion and splendid size for both indoor and outdoor work. Let the dealer show you what a simple and efficient Kodak is the 1A Speed.

EASTMAN SPEED FILM.

This film is made especially for speed work. It is 30% faster than regular film, but this difference in speed is only noticeable when photographing rapidly moving objects with special speed equipment used at highest speed.
