can circulate freely. The strips of crepe are hung close 

 to each other. The rubber must be kept about three 

 weeks in the drying- house, and can then be sent to 

 market. 



c. Inferior qualities. 



The scrap is always made into crepe rubber. This 

 takes place in the same manner as already described, 

 in the crepe machine; by means of a pipe with holes 

 made above the opening between the cylinders; plenty 

 of water is added, so that, by stretching out the scraps, 

 the dirt which is there, is washed away. The crepe 

 thus obtained shows a darker and not so even a colour 

 as the crepe made direct from latex; the scrap consists 

 of lighter or darker brown lumps of rubber, and these 

 shades of colour are found again in the crepe. 



d. Scrap. 



The shavings still contain a small percentage of rubber, 

 not in the tissue but outside, because, after pulling off 

 the scrap, these wounds bleed again, and produce a 

 small quantity of rubber, coagulating on the bark, and 

 sticking to the small strip cut away in the process of 

 tapping. The shavings are worked in the same manner 

 as the scrap ; water should be supplied amply. In this 

 way, a blackish brown crepe is obtained with, here 

 and there, lighter points, which are grains of bark tissue. 



Earth rubber is worked exactly like shavings ; the 

 crepe obtained from it is black.
