On reaching Windermere, on the edge of Lake Windermere, move on to Ambleside, Keswick; thence through Newmarket to Carlisle. Leaving Carlisle, make for the Solway Firth railway bridge, cross on the railroad train, and run up through Dumfries. From this point to Ayr there is a very good road, and at the end of it any one who is an admirer of Burns may study him in his home. From Ayr proceed to Glasgow through Kilmarnock, and from Glasgow the prettiest run is through Dumbarton up the western shore of Loch Lomond; then, following the valley at the north end of the Loch, you will come in time to Tyndrum, and from here it is not a long run to Oban. Here the trip may be further extended up the Caledonian Canal, or the return trip may be made through Stirling to Edinburgh, and thence back to London along the east coast. Such a trip may be completed, including the journey over and back, in from six to eight weeks, and if the method of going to private houses wherever feasible is followed, the expense need not exceed $250.

PREPARATION OF TESTED SENSITIVE PAPERS. NO. 4.--HOW TO MAKE GREEN TONES. Green prints may be made by first making a red print, and then, by the use of nitrate of cobalt, changing the red tone to a brilliant green. The process for making red prints is fully described in No. 850 of the ROUND TABLE, but we repeat the formula, referring the amateur to the paper on red prints for fuller details. Sensitize photographic paper by floating it on a solution made of 96 grs. of nitrate of uranium dissolved in 8 oz. of distilled water. Dry by a gentle heat, and print. This is not a printing-out paper, but the picture is brought out by development. A strong negative requires ten minutes in bright sunlight and two hours in the shade. Remove the print from the frame, and place at once in a dish of hot water for 30 seconds (120° Fahr.). Drain off the water, and lay the print face up in a toning-tray, and flood with a solution made of 40 grs. of red prussiate of potash and 4 oz. of distilled water. Keep the tray in motion so that all parts of the print may be equally affected by the developer. In a few minutes the picture will begin to appear, and will develop up a beautiful red color. Wash this print in several changes of water till no more color runs from it and the washing water is clear. Have ready a ten-per-cent. solution of nitrate of cobalt. Place the red print in this without drying, leave it in for one minute, remove, and, without washing, dry by a fire. The red print will turn to a beautiful green; the more intense the heat used in drying the more brilliant will be the green color. This print is not permanent, but must be made so by immersing in a fixing solution prepared as follows:
