 be at least sufficient to cover the vvhole well. Boil them toge- 

 ther for two or three hours, adding more water from time to 

 time, to supply the place of what is wasted by evaporation. Take 

 out the clo^h thus prepared, wring it, and hang it up to dry 

 without rinsing. 



Afterward, when you would dye the cloth thus prepared, 

 begin by rinsing it carefully in cold vi'ater; then put it into a 

 well tinned copper, with cold river or spring water, and a 

 small quantity of brasil ; and boil it gently for half an hour or 

 an hour, according as you would have the tint deeper or lighter. 

 If too much brasil be used, the dye will have a violet hue. 



Aftier having taken it from the fire, rinse the cloth immedi- 

 ately in cold water. It is not necessary that the bath should 

 have been made to boil ; it is sufficient to keep it for a couple 

 of hours at a heat of 60** or 70" of the centesimal thermome- 

 ter (140^* or 155" Farht).

 used in the same manner with eq\ial advantage. The blue it 

 yields, when it is perfectly dry, is even deeper, which may 

 render it preferable. Hitherto this moss has been applied to 

 no vise but that of making mats, except that the farina of the
