    * , / ' > 'earthen pan somc^ brimstone., over a slow fire, and ■when melted throw in some filings, which keep stirring about till they are covered with brimstone ; this you must do while it is on the fire ; then take it off, and stir it very quick till cold, when you must roll it on a board with a wooden roller, till you have broke it as fine as com powder;' after which sift from it as much of the brimstone, as you can. There is another method of preparing filings, so as to keep two or three months in winter; this may be done by rubbing them between the strongest sort of brown paper, which before has beep moistened with linseed oil. N. B. If the brimstone should take fire, you may put/it out, by covering the pTm close at top. It is not of much signification what quantity of brim¬ stone you use, so.'that there is enough to give each grain of iron & coat; but as much as will cover the bottom of a pan of about one foot diameter, will do for five or six pound of filings. Cast iron for gerbes may be preserved by the above method. Of Water Rockets. Water rockets may be made from four ounces to two pound ; blit if larger they are too heavy, so that it will be difficult to make them keep above water without a cork float, which must be lied to the neck of the case, but the rockets w ill not dive so well with, as without floats. Cases for water rockets are made in the same manner and proportion as sky rockets, only a little thicker of paper; when you fill these rockets, which are drove solid, put in, first, one ladle full of slow fire, then two of the proper charge, and on that one or tvVo lad!efs of sinking charge.; then the proper .charge, then-the sinking.ch^ge .again, and -so on, tilt you have filled the case within three diameters; then drive on the composition one ladle full of clay, through which make a small hole to the charge ; then
