Method of painting Linen Cloth xcith Oil Colours, 



be more pliant, durable, and longer impervious, to 

 Water, than in the usual Mode. By Mr. William 

 Anderson, of his Majesty s Dockyard, Portsmouth *. 



SIR, 



J. BEG leave to lay before the Society of Arts &c. the 

 following improvements and observations, which I hope 

 will be of service to the public. 



Having never heard or read of any method being disco- p^ nt m canvag 

 vered to prevent paint when laid on canvas from harden- hardens and 

 ing to such a degree as to crack and eventually to break the 

 canvas, and render it unserviceable in a short time; and 

 having been an eye-witness for many years of much canvas 

 perishing for want of such discovery in the immense quan- 

 tities painted for covering seamen's hammocks, and for other 

 uses on board his majesty's ships ; I long had it under con- Ingredient ta 



sideration to find out such an ingredient as, when mixed P reve nt this

with paint, would preserve the canvas and paint laid 



thereon from the damages above mentioned, and after 



experiments for a considerable time, I have discovered such 



au article, and made trial of it with effect above three 



years. 



The canvas I have painted has been submitted to the in- 



spection of the Navy Board, who are so perfectly satisfied 



with my new method, that general directions are now given 



to paint all canvas in his majesty's dock-yards in this 



manner; which, in addition to the advantages I have before 



mentioned, actually saves an expense of one guinea in every Saves expense. 



hundred square yards of canvas so painted, as I have fully 



stated to them. The ingredient I use is not only scr- Answers for 



viceable for ship's canvas, but also for canvas designed for P a,n,i,1 ? s , floor 



, . . cloths, &c. 



paintings, for floor cloths, and for painted coverings within 



and without doors. I have no doubt of it being applied to 



many other purposes I am yet unacquainted with ; as from
