On alternate days the scrub team should keep the ball in its possession constantly, in order that the first team may get practice in defensive play. On the other days the first team should hold the ball, in order to develop the strategy of offensive work. It is also well, as the season grows older, to have the regular half-backs play on the scrub team, in order that the rush-line players of the first team may have the advantage of playing against the best backs their schools can turn out.

Any questions in regard to photograph matters will be willingly answered by the Editor of this column, and we should be glad to hear from any of our club who can make helpful suggestions.
A very simple and easy way to color photographs, and one by which a person with little or no knowledge of painting can produce quite pleasing effects, is called the "Hallotype," from the name of the inventor, Mr. J. B. Hall.
The process consists in printing two paper positives from the same negative, rendering one transparent by the use of dammar varnish, and painting the other, and placing the transparent print over the painted one, and fastening them securely between two plates of glass.
To render the print transparent, after it has been toned and dried, lay it face down on a sheet of glass, and varnish with dammar varnish. This varnish can be bought ready prepared, or may be made of one ounce of dammar-gum dissolved in two ounces of spirits of turpentine. If one coat does not make the print transparent enough, apply a second when the first is dry. Be careful that the print, when drying, does not stick to the glass.
Another way to make the print transparent is to apply the print to glass, and remove the paper, leaving the film on the glass. To do this take a spoiled negative or piece of clear glass, clean it thoroughly, and polish it with French chalk to remove all trace of grease. Varnish the glass with varnish made of one ounce of balsam of fir and two ounces of spirits of turpentine. As soon as the varnish begins to set, take the print, which must be thoroughly wet, blot off the moisture from the face with clean blotting-paper, and place the print face down on the glass. Roll down smoothly with a squeegee, taking care that no air-blisters remain between the print and the glass. The paper can now be removed by rubbing it gently with the fingers, moistening it with a wet sponge as it dries. When the paper is removed, varnish the film and set it away to dry.
