TWO:All round the post-office there is invariably a crowd of natives scribbling in pencil on post-cards held in their left hands. Their correspondence is lengthy, minute, and interminable; in spite of their concentration and look of reflection I could never bring myself to take them seriously, or feel that they were fully responsible for their thoughts and actsmachines only, wound up by school teaching, some going out of order and relapsing into savages and brutes.

Hydrocyclone (liquid cyclone)02

A hydrocyclone (liquid cyclone) injects treatment solution into stationary equipment to perform separation, classification, and concentration, and is an innovative separator with a very simple structure and no drive unit.

Structure of a hydrocyclone (liquid cyclone)

A suspension containing fine particles of several micrometers or more is supplied to a cylindrical container circumferentially at high speed. And as a result it starts to rotate and a centrifugal force is generated. At this time a gravitational acceleration of several tens of thousands of G is generated in the circumferential direction, and thus leading to fast sedimentation and concentration of the fine particles. The separated concentration can be freely selected by changing the supply rate (supply pressure and flow rate) and the flow ratio of the outlet. Our hydrocyclone (liquid cyclone) was designed and manufactured to classify and concentrate fine particles, and so has a small element.

THREE:The pile of the girl with marigold wreaths and the shroud stained crimson and purple flung her ashes to the winds, reduced to mere atoms of bone and light cinder, and the servants of the place drowned a few still glowing sticks in the river;[Pg 169] the family and friends slowly went up the yellow stone steps and disappeared through a gateway leading into the town.Abibulla saw them off with great deference and a contrite air, and watched their retreat; then, as[Pg 260] I was about to send him to despatch the message, he was indignant. The police! What could they do to a sahib like me? It was all very well to frighten poor folksit was a sin to waste money in asking for a reply which I should never be called upon to showand so he went on, till I made up my mind to think no more of the matter. And whenever I met the chief at the bazaar or by the Jellum, he only asked after my health and my amusements.

THREE:In the evening at Byculla, in the street of the disreputable, in front of a house hermetically closed, and painted with a round red spot for each person who had died there, a fire of sulphur was burning with a livid glow. Only one gambling-house tried to tempt customers with a great noise of harmonium and tom-toms; and from a side street came a response of muffled tambourines and castanets. First the dead, wrapped in red stuff and tied to a bamboo, and then the procession turned into the lighted street. White shapes crowded by, vanishing at once, and the harmonium again rose above the silence with its skipping tunes, and the tom-toms beating out of timeand attracted no one.
