been worked more extensively in America, where in 1885 they were something of a craze. By com¬ bining the portraits of 152 members of an American masonic lodge an American worker has beaten a previous record of 51 — a composite portrait of this number of bank managers — which took from De¬ cember 10th, 1908, to July 27th of the following year to complete. Such portraits are claimed to be of scientific value to students of anthropology, but they are more generally looked upon as curiosities.
The Camera in Law.
There is some suggestion that the police should carry cameras to record
the results of any road accident, the idea being that the photographic evidence would be incontrovertible, even though the camera could not be put upon its oath. The camera is used to detect forgeries in docu¬ ments, for it can be said from photo¬ graphic evidence if a signature was written before the document itself, provided only, of course, that the strokes of the two pieces of writing overlap ; though after Dr. D. A. Spencer’s recent lecture on the fallacies which a photograph may perpetuate we find ourselves a little unwilling to condemn a sup¬ posed forger to penal servitude on the strength of photographic evi¬ dence.

Houghton Mill Saved.
One of the most pictorial water¬ mills in England, and perhaps the most photographed, is Houghton Mill, near St. Ives, Hunts. Rumours of its demolition have been current for some years, but it was stated officially a few days ago that the old mill is to be saved. An offer of a ninety-nine years’ lease has been made to the inhabitants of the village, on certain conditions. These have been accepted, and a committee has been formed to raise the neces¬ sary funds to repair the roof. The mill has for generations been a favourite subject for camera-men and artists of the pen, pencil and brush.

EVERY MONTH a brief exposure table will be provided for the assistance of our readers in their practical work. A glance at the current approximate exposures as here given will serve as a reliable guide for most purposes. The subjects will be varied to suit the time of year. The following exposures will serve as a working guide for any fine day during the month, between the hours of 10 in the morning and 2 in the afternoon, with the sun shining, but not necessarily on the subject. Stop used, f/8. The exposure should be doubled if the sun is obscured or if stop f/n is used. For f/16 give four times the exposure. For f/5.6 give half. From 8 to 10 a.m. or from 2 to 4 p.m. double these exposures. From 7 to 8 a.m. or from 4 to 5 p.m., treble them.
