ear, April 16, June 15, Sept. 2 and Dec. 25, and on these dates the dial needs no correction. The corrections for the various days of the month can be taken from Table 3. The + means that the clock is faster, and the means that the dial is faster than the sun. Still another correction must be made which is constant for each given locality. Standard time is the correct time for longitude 750 New York, 900 Chicago, 1050 Denver and 1200 for San Francisco. Ascertain in degrees of longitude how far your dial is east or west of the nearest standard meridian and divide this by 15, reducing the answer to minutes and seconds, which will be the correction in minutes and seconds of time. If the dial is east of the meridian chosen, then the watch is slower; if west, it will be faster. This correction can be added to the values in table No. 3, making each value slower when it is east of the standard meridian and faster when it is west. The style or gnomon with its base can be made in cement and set on a cement pedestal which has sufficient base placed in the ground to make it solid. The design of the sundial is left to the ingenuity of the maker. --Contributed by J. E. Mitchell, Sioux City, Iowa. Table No. 3 Corrections in minutes to change.

The designs shown represent original arms of the sixteenth and seventeenth centuries. As they are the genuine reproductions, each article can be labelled with the name, adding to each piece interest and value, says the English Mechanic, London. Each weapon is cut from wood. The blades of the axes and the cutting edges of the swords are dressed down and finished with sandpaper an
