These are driven into turned wooden tubes of 

 beech, in the most regular manner, and with the 

 o-reatest force possible, The tube has a cup for prim- 

 ing and quick match, is closed at the opposite end, 

 and is six inches long. An inch, or any given length, 

 must burn a definite time, or else the fuse is rejected. 

 The time of bursting of the shell is calculated on this, 

 and on the time of flight. The tube is cut off to the 

 calculated length at the moment when it is required.

The same: A better Composition. 

 The tow or flaxrope is boiled in a solution of sugar 

 of lead, in the proportion of six drachms to a pint of 

 water, for a few minutes, and dried. A convenient 

 match is also made by rolling the blue paper used for 

 suo-ar-loaves, into cylinders resembling candles, and 

 soaking them in the same solution. 



Third Composition. Old Slow Match. 

 The tow-rope is boiled for some hours in a mixture 

 of lye and quicklime. 



Of Iron RocJcets. 



These rockets, known by the name of Congreve Of iron 

 rockets, have become greatly celebrated, from their rockets. 

 having been used on various occasions in our late war. 

 The first use of them, we believe, was at the bombard- 

 ment of Copenhagen, where they were said to have 

 set fire to many nouses. After this they were used 

 against the Boulogne flotilla, and against Flushing. 

 Not to enumerate the multitude of instances where 

 they have been applied to various kinds of service, we 

 shall only further remark, that they were used with 

 great success against cavalry at the first battles of 

 Leipsic, by the Anglo-Russian troops, and at the af- 

 fair of Bayonne. 



For military purposes, they are used in different Used for 

 modes. If they are intended against towns, or works, military 

 they are furnished either with a shell or a carcase, ac- purposes. 

 cording to circumstances. In the latter case, how- 

 ever, a separate carcase is not used ; but the composi- 

 tion is placed immediately in the conical iron cap, 

 which is furnished with holes, to permit the flame to 

 pass out. In this way a rocket of moderate dimen- 

 sions is enabled to carry a considerable quantity of 

 combustible matter, and in a very convenient form. 

 Such carcase rockets are particularly useful against 

 shipping, as they may be fired from small boats, and 

 thus brought into shoal water, or over bar harbours, 

 where large mortar vessels could not be used. Thus 

 also they may be used in the night, or in calms ; as 

 small boats can approach a vessel at anchor, or other- 

 wise, under those circumstances where a larger class 

 of shipping would be useless. But we need not point 

 out the numerous cases in military service, where 

 rockets of this nature may be advantageously adopted, 

 when mortars for throwing carcases or shells would 

 be unattainable or incapable of being used. 



Their use in the field is of a different nature, and 

 they may be applied either for the purpose of injuring 

 the enemy directly, or for that of disordering his ca- 

 valry by exciting alarm. In the former case they are 

 thrown, in the same manner as against works, at a
