Tennis Courts may be Laid Out Quickly by the Use of a Wheelbarrow to Which a Can Containing a Thin Lime Mixture has been Fixed, as Shown
Many home tennis courts are not provided with a marker, and the use of a wheelbarrow for this purpose has been found convenient. A can provided with hooks at its upper edge was attached to the front of the wheelbarrow, as shown in the sketch, and the lime mixture, very thin, poured into it. Holes were made at the lower edge of the can so that the liquid ran onto the wheel and was transferred to the court. The holes must be made large enough so that they will not clog quickly, and the mixture must be very thin. It is easy to cover the outline several times if necessary. Hence, to use a thin mixture will be found economical, rather than to waste time removing sediment from the spout.
Retouching Negatives for Printing
Portraits taken out of doors sometimes show unusually heavy shadows under the eyebrows and chin. The printing of these through the negatives may be altered by applying a little red or blue color on the glass side of the negative. Stippling the surface by contact with the texture of the skin also aids in removing the heaviness of such shadows.
Mat varnish, containing a small amount of iodine dissolved in it, and applied to the glass side of a negative, will cause much lighter prints than if the negative is permitted to remain with heavy shadows. The varnish will dry quickly, and it may then be scraped off carefully or removed with benzole from the parts of the negative which are not to be lightened. Care must be taken in scraping away the varnish in order to prevent scratches.
Hand-Operated Whirling Fan
The whirling fan illustrated is more convenient than a fan of the ordinary type, and may be made by a boy of only moderate mechanical skill. The materials necessary for its construction are easily available in the home. The sketch at the center shows the completed fan, and the smaller sketch at the right illustrates the method of operation. The details of construction are shown in the working drawings.
The Whirling Fan Is Superior to One of the Ordinary Variety and may be Made at Home of Materials Readily Available. The Small Sketch at the Right Shows the Method of Operation, and the Details of Construction are Shown in the Larger Sketch and in the Working Drawings
The wing of the fan is cut from a sheet of Bristol board, and is 6 in. long and 5¹⁄₂ in. wide. It is formed by gluing two pieces together, the upper end of the driving shaft being glued into place at the same time. The small sketch at the left shows the size and shape of the piece of wood into which the driving shaft is fastened at its upper end.
