A Living God by Lafcadio Hearn

A Living God by Lafcadio Hearn Short Summary of the Lesson in Three Parts Part I – Summary (≈150 words) The first part of the lesson describes the structure and spiritual significance of Shintō shrines in Japan. These shrines are simple buildings made of unpainted wood with steep roofs and lattice doors. Because they are left unpainted, the wood gradually turns gray under the influence of sun and rain, blending naturally with the surrounding landscape. According to Shintō belief, these shrines are the dwelling places of divine spirits called Kami. Many of these spirits are believed to be the souls of great warriors, rulers, or ancestors who lived long ago. The author explains that the mysterious emptiness of these shrines often creates a strange and supernatural feeling in visitors. Standing alone before such a shrine may give one the impression of being watched by invisible beings. The author even imagines what it might feel like to be a god living in a shrine and receiving prayers fr...

Technical Description of an Air Cooler (Unit four)

 Technical Description of an Air Cooler

An air cooler is a domestic appliance used for cooling the air of the room in summer season. It utilizes water vapour to cool the atmosphere of the room. The air inside the cooler is cooled by water circulation through the grass pads on its body and the cooled air of the cooler is driven out into the atmosphere by a cooler fan or an exhaust fan.

Different types of coolers made of steel sheet or plastic fibre are available in the market. These coolers may be divided into the following two categories:-

Room Cooler

A room cooler is made of steel sheet or plastic fibre. (People prefer plastic fibre now for safety reasons.) It looks like an upright box having a cooler fan or an exhaust fan on its front face and three screens on the remaining faces. The three screens have grass pads of khus grass or plastic fiber for soaking water. It has a storage tank for water at its bottom and a dispenser tank on its top. The dispenser tank may be closed by a lid or sometimes it does not have any such lid. The storage tank has a water pump at the bottom or a submersible water pump submerged in the water of the tank. The water pump pumps the water of the tank through a plastic tube on to the dispenser tank.

The dispenser tank has perforations placed just over the three screens. The water of dispenser tank falls on the three screens and trickles down into the storage tank after moistening the grass pads. The extra water of the dispenser tank may flow through another plastic tube into the storage. The soaked grass pads evaporate water vapor and cool down the air inside the cooler, which is driven into the atmosphere of the room by a cooler fan or an exhaust fan. The room cooler has wheels at the bottom, which make it portable to any room of the home.


Window Cooler

A window cooler is very much similar to a room cooler. The difference is that it is mounted on the window of the room and it provides better cooling effect than a room cooler because it gets dry air from the atmosphere.

It does not have wheels at the bottom. Besides this, it does not have a dispenser tank but a dispenser tube instead of it. The dispenser tube is placed over the three screens. It has perforations for dispensing the water on the screens.

An air cooler comes cheaper than an AC. However, it fails during rainy season due to high level of humidity.

Uncle Podger Hangs a Picture by Jerome K. Jerome

  Uncle Podger Hangs a Picture You never saw such a commotion up and down a house, in all your life, as when my Uncle Podger undertook to do a job. A picture would have come home from the frame-maker's, and be standing in the dining-room, waiting to be put up; and Aunt Podger would ask what was to be done with it, and Uncle Podger would say: "Oh, you leave that to me. Don't you, any of you, worry yourselves about that. I'll do all that." And then he would take off his coat, and begin. He would send the girl out for six penny worth of nails, and then one of the boys after her to tell her what size to get; and, from that, he would gradually work down, and start the whole house. "Now you go and get me my hammer, Will," he would shout; "and you bring me the rule, Tom; and I shall want the step-ladder, and I had better have a kitchen-chair, too; and, Jim! You run round to Mr. Goggles, and tell him, 'Pa's kind regards, and hopes his leg's be...

My Financial Career by Stephen Leacock

My Financial Career  by Stephen Leacock When  I go into a bank I get rattled. The clerks rattle me; the wickets rattle me; the sight of the money rattles me; everything rattles me.  The moment I cross the  threshold of a bank and attempt to transact business there, I become an irresponsible idiot.  I knew this beforehand, but my salary had been raised to fifty dollars a month and I felt that the bank was the only place for it.  So I shambled in and looked timidly round at the clerks. I had an idea that a person about to open an account must consult the manager. I went up to a wicket marked 'Accountant'. The accountant was a tall, cool  devil.  The very sight of him rattled me. My voice was sepulchral.  'Can I see the manager?' I said, and added solemnly, 'alone'. I don't know why I said 'alone',  'Certainly,' said the accountant and fetched him.  The manager was a grave, calm man. I held my fifty-six dollars clutched in a crumpled b...
