During the Great Depression from 1929 to 1932, rabbit trapping was a means of survival for many people. Rabbits provided meat and pelts which were sold for making felt hats such as the Akubra. Rabbit populations are controlled in the 21st century by poisoning, destroying or 'ripping' burrows (warrens), biological control with rabbit haemorrhagic disease and myxomatosis, and by shooting. Rabbit-proof fences also prevent the spread of rabbits into some areas. (ref. Powerhouse Museum) Steel-jawed rabbit traps were widely used in urban and rural Australia from 1880 to 1980. This trap is symbolic of the battle that Australians have waged against burgeoning rabbit populations for over a century. Rabbits cause enormous damage to Australian soils and biodiversity. The introduction of rabbits to this country was an environmental disaster.Two iron rabbit traps. Each consists of a pair of jaws held closed by spring tension and a triggering mechanism. When the trap is triggered the jaws close over the top of the bridge, plate and tongue mechanism that is designed to trigger the trap. A chain is attached by a hook on the bent end of the trap's spring with a long steel spike looped over the last link of the other end of the chain. The trap is designed so that the metal jaws snap shut against each other when the trap is activated by the application of weight to the pressure plate. In use, traps are set with open jaws, buried lightly just below the surface of the earth. When an animal steps on the pressure plate, the jagged teeth of the jaws snap around the animal's leg, usually breaking bone and sinew. Thus the animal is immobilised.rabbits rural trapping

Iodine is an essential trace element for life, the heaviest element commonly needed by living organisms. In medicine, potassium iodide is usually used to treat acute thyrotoxicosis. Hyperthyroidism, an overactive thyroid, is a condition in which the thyroid gland produces and secretes excessive amounts of the free (not protein bound, and circulating in the blood) thyroid hormones, This is the opposite of hypothyroidism ('sluggish thyroid'), which is their reduced production and secretion. Graves' disease is the most common cause of hyperthyroidism. Iodine's main role in animal biology is as a constituent of the thyroid hormones thyroxine If there is a deficiency of dietary iodine, the thyroid will not be able to make thyroid hormone. The lack of thyroid hormone will lead to decreased negative feedback on the pituitary, leading to increased production of thyroid-stimulating hormone, which causes the thyroid to enlarge (the resulting medical condition is called endemic colloid goitre This has the effect of increasing the thyroid's ability to trap more iodide, compensating for the iodine deficiency and allowing it to produce adequate amounts of thyroid hormone. The thyroid hormones are essential to proper development and differentiation of all cells of the human body. These hormones also regulate protein, fat, and carbohydrate metabolism, affecting how human cells use energetic compounds. They also stimulate vitamin metabolism. Natural sources of iodine include sea life, such as kelp and certain seafood, as well as plants grown on iodine-rich soil. Iodized salt is fortified with iodine. Elemental iodine is used as a disinfectant in various forms. It is a wound cleaner and Iodine also acts as an expectorant of mucous from the common cold and other respiratory ailments. Iodine is a common aid for skin conditions, such as acne, ..A brown glass triangular shaped bottle with a plastic screw top lid that contained IodineFront Label : SANA / TINCTURE WEAK (2 1/2 % ) / IODINE / POISON / ANTISEPTIC COUNTER / IRRITANT ETC. / THE SANAX CO. / 5 BRUNSWICK STREET FITZROY / TEL.
