A composition used for wheels. 



The effects of all these are alike, and they merely 

 differ in strength. But it would simplify the business 

 much, to take only one of these, such as No. 1 . and to 

 make it stronger or weaker as may be required, by 

 altering the proportions of the charcoal.

A strong brilliant fire for any purpose, and chiefly for gerbes. 



It is unnecessary to enumerate more of these spark- 

 ling compositions, as indeed one-half of these are more 

 than sufficient for use. It depends on the taste and 

 judgment of the artist to select those which on trial 

 may please him best. It is always necessary, at any 

 rate, to try the effect of a fire before using it ; and if 

 it is not liked, it may be modified at discretion. We 

 should also recommend in this case, as in the former, 

 to choose one or two compositions, such as Nos. 1, 2, 

 8, and merely alter their strength by different propor- 

 tions of mealed powder. 



All these require to be mixed with gum water. We 

 e suppressed the numerous other receipts in the 

 books, as they produce no effects different from the 

 above.
