Sydney Water in 1788 Was the Little Stream That Wound Its Way from Near a Day Tour of the Water Supply Hyde Park Through the Centre of the Town Into Sydney Cove
In the beginning Sydney’s first water supply from the time of its settlement Sydney Water in 1788 was the little stream that wound its way from near A day tour of the water supply Hyde Park through the centre of the town into Sydney Cove. It became known as the Tank Stream. By 1811 it dams south of Sydney was hardly fit for drinking. Water was then drawn from wells or carted from a creek running into Rushcutter’s Bay. The Tank Stream was still the main water supply until 1826. In this whole-day tour by car you will see the major dams, canals and pipelines that provide water to Sydney. Some of these works still in use were built around 1880. The round trip tour from Sydney is around 350 km., all on good roads and motorway. The tour is through attractive countryside south Engines at Botany Pumping Station (demolished) of Sydney, and there are good picnic areas and playgrounds at the dam sites. source of supply. In 1854 work started on the Botany Swamps Scheme, which began to deliver water in 1858. The Scheme included a series of dams feeding a pumping station near the present Sydney Airport. A few fragments of the pumping station building remain and can be seen Tank stream in 1840, from a water-colour by beside General Holmes Drive. Water was pumped to two J. Skinner Prout reservoirs, at Crown Street (still in use) and Paddington (not in use though its remains still exist). The ponds known as Lachlan Swamp (now Centennial Park) only 3 km. -

No part of this book may be distributed, posted, or reproduced in any form by digital or mechanical means without prior written permission of the publisher. 1 Introduction 1.1 AN INTRODUCTION TO RADIO ASTRONOMY 1.1.1 What Is Radio Astronomy? Radio astronomy is the study of natural radio emission from celestial sources. The range of radio frequencies or wavelengths is loosely defined by atmospheric opacity and by quantum noise in coherent amplifiers. Together they place the boundary be- tween radio and far-infrared astronomy at frequency ν ∼ 1 THz (1 THz ≡ 1012 Hz) or wavelength λ = c/ν ∼ 0.3 mm, where c ≈ 3 × 1010 cm s−1 is the vacuum speed of light. The Earth’s ionosphere sets a low-frequency limit to ground-based radio astronomy by reflecting extraterrestrial radio waves with frequencies below ν ∼ 10 MHz (λ ∼ 30 m), and the ionized interstellar medium of our own Galaxy absorbs extragalactic radio signals below ν ∼ 2 MHz. The radio band is very broad logarithmically: it spans the five decades between 10 MHz and 1 THz at the low-frequency end of the electromagnetic spectrum. Nearly everything emits radio waves at some level, via a wide variety of emission mechanisms. Few astronomical radio sources are obscured because radio waves can penetrate interstellar dust clouds and Compton-thick layers of neutral gas. Because only optical and radio observations can be made from the ground, pioneering radio astronomers had the first opportunity to explore a “parallel universe” containing unexpected new objects such as radio galaxies, quasars, and pulsars, plus very cold sources such as interstellar molecular clouds and the cosmic microwave background radiation from the big bang itself. -
Fishing Malgun
Aboriginal Heritage Office Yarnuping Education Series Ku-ring-gai, Lane Cove, North Sydney, Northern Beaches, Strathfield and Willoughby Councils © Copyright Aboriginal Heritage Office www.aboriginalheritage.org Yarnuping 9 - Women and Salt Water Country – Fishing Karen Smith & Phil Hunt Sydney Aboriginal women are too often forgotten in the stories of Bennelong and other Sydney men of the late 1700s, early 1800s. I wanted to bring them to the fore in this Yarnuping about Saltwater Women. You will note that the commentators are largely men, which adds further imbalance to the story, so we must take things with a grain of salt. Malgun The Aboriginal custom of female finger- tip removal – 'malgun', “the finger is taken off by means of ligature (generally a sinew of a kangaroo) tied so tight as to stop the circulation of the blood, which induces mortification and the part drops off. I remember to have seen Colbee’s child, when about a month old, on whom this operation had just been performed by her mother.” Watkin Tench 1788 page 248 For example, Captain Arthur Phillip, of the First Fleet, interpreted finger tip removal as follows: “It was now first observed by the Governor that the women in general had lost two joints from the little finger of the left hand. As these appeared to be all married women, he at first conjectured this privation to be part of the marriage ceremony; but going afterwards into a hut where were several women and children, he saw a girl of five or six years of age whose left hand was thus mutilated; and at the same time an old woman, and another who appeared to have had children, on both of whom all the fingers were perfect. -

The location of the development is approximately five kilometres from the southern urban fringe of the Campbelltown local government area, six kilometres northwest of Appin village, between about two and three kilometres west of Appin Road, and between 600 m and two kilometres east of the Nepean River. This report provides a desktop review of historical heritage places in the vicinity of the proposed gas turbine power station, and the station’s impact on the heritage significance of those places. Those places include, ‘Meadowvale’ and ‘Mount Gilead’ homesteads, and the Sydney Water Supply Upper Canal system. Findings The study found that: ‘Meadow Vale’: Is classified as an historic site by the National Trust of Australia (NSW); Fulfils NSW Heritage Office significance criteria a (historical), b (personal association), e (research) and g (characteristics) and has moderate heritage significance for heritage listing at a local level; The distant landscape context of Meadow Vale and has little heritage -
