A Coat Of Iron Rods

I have been stimulated by the recent trials of the bullet proof cnirass to try a few experiments on the subject. I will only mention one experiment, which I made this morning, assisted by several members of the Junior Scientiflc club hert). It occurred to me that, if the energy of the bullet could be made to act at rather a large angle to its line of fiight, its peuetrating power would be diminished. To effect this I arranged a number of soft iron rods one-quarter inch in diameter and 5 iuches long side by side and touching a piece of deal board. On these another layer was placed, so that one of the upper rods touched two of the nnder ones. A sheet of thin rubber onesixteenth of an inch thick placed on this eeparated it from asimilar combination attached to it at right angles, and the whole formed the target. The rifle used was a wiuchester, 22 bore, carrying a long bullet. At a distance of 20 feet the bullet penetrated f5 ve inches of hard pine with certainty, but wheu the bullet, fired at the same distance, hit my rod target it failed to penétrate even the first layer, but only drove the upper rods aside uearly at right angles to the line of flight. The next experiments will be made with heavier materials and largershot. Pospibly a similar arrangement, but of large steel cylinders. might make a satisfactory barrier to the shots of big guus. -
