We have had several inquiries about the George Junior Republic at Freeville, and are pleased to say that the young citizens are being received there in as large numbers as the funds will permit.

It might interest our readers to know that any one sending $15 to Mr. A.G.  Agnew, Treasurer of the George Junior Republic, 7 Nassau Street, New York, can give a ten-weeks’ holiday to one poor little lad of the streets.

It is a very small amount of money to do so much good with, and it is to be hoped that people who have $15 to spare will send it to the Junior Republic to help the good work along.

INVENTION AND DISCOVERY.

RECORDING THERMOMETER.—­This is a very interesting little machine, especially so at this time of year when the temperature is a constant subject for thought.

[Illustration:  Thermometer]

It is a recording thermometer, and consists of a thermometer and a recording disk.  By means of cleverly arranged mechanism the rise and fall of the mercury is used as the motor power, and registers the changes in temperature on an indicator card.  Other simple mechanism works a rotary drum by which this indicator card is carried.

PENCIL SHARPENER.—­This is another helpful little contrivance, a pencil sharpener.  There are already numberless things of the kind, some of which answer for a time, some not at all, and all being made for the purpose of sharpening the pencil to a kind of regulation point.  For my own part I have always preferred a good sharp knife, or the simple reason that I could then make exactly the kind of point suited to the work to be done.  The purpose of the new pencil sharpener is evidently the same.  This contrivance is a small and handy block for holding the pencil in position for the knife, and has a cutting guide which will be a joy to people who are awkward in using the knife.

COLORED PHOTOGRAPHY.—­The State Department has received a specimen from Paris of Mr. Villedieu Chassaigne’s work in colored photography.

The claim made by Mr. Chassaigne is that he can photograph objects in their exact colors.

The coloring process is applied after the picture has been developed and the print made.

A colorless liquid is then applied to the print, and after that it is washed again in blue, green, and red liquids.  After each application the print is wiped dry.  The various parts of the picture choose their original colors, and the result is an exact representation of the object photographed.

Several pictures have been brought over by Mr. Anthony, of New York.  Among them were several portraits in which the flesh tints and the colors of the clothing were beautifully rendered.  A view of the Jardin d’Acclimatation in Paris showed a group of storks, the red coloring of their legs and beaks being distinctly visible.
