Thus far, however, the calculation is limited merely as to the bare question of expense; but on the score of general advantage, how is not the balance augmented in favour of the Rocket, when all the _exclusive_ facilities of its use are taken into the account--the _universality_ of the application, the _unlimited_ quantity of instantaneous fire to be produced by it for particular occasions--of fire not to be by any possibility approached in quantity by means of ordnance? Now to all these points of excellence one only drawback is attempted to be stated--this is, the difference of accuracy: but the value of the objection vanishes when fairly considered; for in the first place, it must be admitted, that the general business of action is not that of target-firing; and the more especially with a weapon like the Rocket, which possesses the facility of bringing such quantities of fire on any point: thus, if the difference of accuracy were as ten to one against the Rocket, as the facility of using it is at least as ten to one in its favour, the ratio would be that of equality. The truth is, however, that the difference of accuracy, for actual application against troops, instead of ten to one, cannot be stated even as two to one; and, consequently, the compound ratio as to effect, the same shot or shell being projected, would be, even with this admission of comparative inaccuracy, greatly in favour of the Rocket System. But it must still further be borne in mind, that this system is yet in its infancy, that much has been accomplished in a short time, and that there is every reason to believe, that the accuracy of the Rocket may be actually brought upon a par with that of other artillery ammunition for all the important purposes of field service. W. CONGREVE. Transcriber’s Notes Punctuation and spelling were made consistent when a predominant preference was found in this book; otherwise they were not changed. Simple typographical errors were corrected. Ambiguous hyphens at the ends of lines were retained; occurrences of inconsistent hyphenation have not been changed. In the table of Ranges: Transcriber rearranged parts of the column headings, but “as follow” (singular) in the table’s title was printed that way in the original. The column heading “55 to 60°” was misprinted as “55 to 66°”; corrected here. End of the Project Gutenberg EBook of The Details of the Rocket System, by William Congreve
