Tree lace

Latex continues to drip after the initial collection and coagulates naturally in the cup to form cup lump. Coagulum which forms as a film of latex on the tapped cut, called tree lace, or from latex that has dripped onto the ground, called earth scrap, is collected the next day along with the cup lump. Some smallholders may not collect the latex at all, but allow it to coagulate in the cup and collect it as cup lump. AH these methods produce mbber known as field coagulum. 

Four types of coagulum are collected in the field, namely cup lump, tree lace, earth scrap and smallholders lump. Cup lump is the coagulated material found in the collection cup formed from residual latex after the latex was collected from a previous tapping. It is a cleaner material than the other three. Tree lace is the coagulum strip that the tapper peels off from the previous cut before making a new cut. It is often contaminated by manganese from the bark and... 

Latex not sold as latex concentrate and cup lump, tree lace, and earth scrap are used to produce various grades of dry rubber. 

The cup lump, tree lace, and earth scrap can be worked up into rubbers called brown crepes . These raw materials vary a great deal in quality and are often dirty, Preliminary treatment frequently includes soaking overnight in a dilute solution of sodium bisulfite to reduce the surface dirt and lighten the color. The material is then macerated and conveyed to a series of roll mills driven at friction speed and fitted with water sprays that clean up the rubber and blend it. The rubber is then sheeted off and dried like smoked sheet. Remilled blanket crepes refers to rubbers similar to brown crepes but which are made of smoked sheet cuttings, smallholders partially dried sheets, and other pieces. The production of brown crepes and remilled blanket crepe is diminishing as demand for technically specified rubber increases and technically specified rubbers use the same raw rubbers that go into crepes and blanket crepes. 

Mr. Harford backed away, gesturing excitedly. He had reached the edge of the wood and entered the trees, so that his neckcloth and the fall of lace at his wrists shone eerily in the gloom. The temple, he said, will be about here. And behind it a knoll, a few trees, spring flowers. The perfect summerhouse for the ladies—for all sorts of assignations. He smiled suggestively. 

Paraffinic oil is a refined petroleum distillate. This pesticidal oil is effective against aphids, lace bugs, leafhoppers, leafminers, mealybugs, scales, psyllids, whiteflies, thrips, and mites on vegetables, fruit and nut trees, landscape trees, shrubs, and flowing plants.
