Saps and Exudations. 



Coagulation— This can be done in pans or tubs, with the aid of a little Acetic 

 Acid, say one volume of pure acid to 100 volumes of pure latex with a little water 

 which will in no way injure the rubber. This will take 8 to 16 hours. Latex coagu- 

 lated in tubs on pivots with a little water and acetic acid well mixed insures evenness 

 of quality of that particular collection, besides saving a great deal of space, also the 

 latex is easily measured and the coagulated mass is quite easily cut into convenient 

 chunks for the crepe machine. The Michie Golledge coagulator is a very quick and 

 satisfactory coagulator, taking only a few minutes in the process. 



Coagulating by smoke, as done in the Amazonas, is quite in its experimental 

 stage, but samples of rubber so cured are undeniably stronger and better preserved 

 than ordinary cures. A process is wanted to smoke, coagulate and cure the latex at 

 one and the same time. The rubber is cured by the Natives in the Amazon on a stick 

 or paddle that they dip continuously into the latex, kept revolving' in the smoke so 

 that each layer of the rubber is smoked and the whole is cured right through and 

 not on the surface only. 



Packages and Packing—Strong boxes or cases any size from 1 to 2 cwt. No 

 paper or other material should be used. It must be remembered that rubber packed 

 in a damp condition arrives mouldy and sticky, and that heat and tackiness nearly 

 always spread and where mixed with sound rubber invariably spoil it. 



Sorting.— As far as possible, even as regards both quality and colour. Pale 

 should be kept from dark and any inferior thrown out and sent home separately. 



Drying. —Great care should be taken to ensure thorough drying, so that 

 biscuits and sheets especially should be dried right through and not superficially 

 only. Badly dried biscuits and sheets sweat, and the resin exudes and causes mould 

 and very often stickiness on the voyage. 



Marking.— Block, Biscuits and Sheets and all cases should be stamped with 

 the Estate or Company mark. 



Alloivances— Landed Terms. — The old East India terms have been done away 

 with, and the only allowance now is £ % Draft, actual tare, and 2£ % Discount.
