in the centre of the piston. The power is sufficien+lv ereat and 

 can be augnieiited at pleasure. As it regards the number of bricks 

 that can be pressed with it per day, we have not been informed. 

 For this, the cost of the machine, and other particulars, we refer 

 those who wish to inquire, to the Inventor, Mr. John Howe, of

PITCH SYRINGE. 



Plate IV. Fig. 2. is a representation of Flint^s Syringe, for 

 paying or filling the seams of ships, or other vessels, with pitch, — 

 a very simple, but very useful invention. It is made like a com- 

 mon syringe, excepting one extremity is curved, in such a manner, 

 that the orifice A, is at right angles with the main body, or tube. 

 B, represents the handle. The Syringe is made of brass, or com- 

 position, and sufficiently laige to hold a quart. It is filled with 

 pitch in the same manner as any syringe would be, by placing the 

 orifice A, into it, and a vacuum made by drawing up the handle B. 

 The end at A, is about two inches long and one-fourth of an inch 

 thick ; but it may be removed, and others of different sizes put 

 on, should a larger or smaller one be necessary. When filled, the 

 end is placed in the seam to be pitched ; pressure is applied to 

 the handle , and at the same time, it is passed along the seam, 

 until all the pitch is forced out. As the pitch is used hot, to pre- 

 vent burning the hand, an exterior tube is fitted on, somewhat 

 larger than the Syringe. For further particulars, apply to Daniel 

 Flint, Nobleboro"', Lincoln Co. Me. 



JONES, ON JAPANNING AND VARNISIIING....N0. 4. 



Improved mode f>f applying the varnish in the French polish. 



To the information given in our last number, on the subject of 

 the French polish, we add the following improvement, made by 

 Mr. Samuel Nock, and published in the Technical Repository : 



" This im[»rovement consists in the substitution of a sponge, with 

 a smooth surface, in place of the coil of list of woollen cloth, or 

 drugs!;et, commonly used. 



" Mr. Nock finds the sponge to be far more convenient, for ap- 

 plying the varnish to the surfaces of gun-stocks, than the list, or 

 drugget ; as it has no loose hairs, like the latter articles, which are 

 continually protruding through the linen cloth?, in which they are 

 enclosed, to the great injury of the process. He also finds, that 

 he can fill the sponge at once 'with a considerable quantity of the
