PORTABLE SUN sundials - Page 7

He has produced a collection of value, containing several rare sundials which money could not buy, for there are but two or three originals in the world. More remarkable is the accuracy with which the copies have been made, because he did not have access to originals and for that matter except in a few in-stances, there were no drawings to aid him only photo-graphs. We are grateful to him for allowing us to photograph and describe his collection for you. Hats off to Bolster. He has set the pace for others. Briefly the Bolster collection contains the following sundials 1 "Egyptian," i hemicyclium, 2 horizontal, 3 "Roman," 2 vertical, 2 cross, 2 ring, 2 universal ring, 2 disk, i "ship," i quadrant, 2 analemmatic, 3 pillar, 2 chalice, i multiface, and i card sundial a total of 28, but he has made 48 in all. We hope his friends appreciate their gifts. All of the sundials in this collection have been figured for use at his home, and in addition many of them show standard time, in one way or an-other. For such a small collection a great variety of materials is represented brass, bronze, cardboard, plaster of paris, cop-per, and wood. Bronze meter covers, copper bus bars, or anything else lying around loose has been used in making these sundials. Of particular interest is the small copper portable cross sundial. The base is fitted with leveling screws and a compass. The cross is adjustable to various latitudes and is self setting. At its left a brass ring sundial is in use. The time of day is pointed out by the position of a beam of light on the inner surface of the ring, as in the universal ring, lower right center, beside which is one of the "Roman" sundials used about 100 A.D.
