cotton bags and were worn beneath the woman’s clothing to keep warm. These women spend most of the day for six months each year feeding, tending, unwinding, spinning, weaving, dyeing and embroidering silk. These women kept the secrets of sericulture for many years. Because the process of “Silk” (sericulture) was so guarded by Chinese authorities it was dominated by them for more than two thousand years. Despite this, we know that one species, out of many varieties of wild silk moths, the Bombyx Mori, dominates China’s production of silk. The Bombyx Mandarina that lived in the white mulberry trees, unique to China, is thought to be the original ancestor of the Bombyx Mori. This species is a blind and flightless moth that lays more than five hundred pinpoint eggs in four to six days. 30,000 worms are formed from one ounce of eggs and eat a ton of mulberry leaves, multiplying their weight by 10,000 times in one month. Around twelve pounds of raw silk is produced by this amount of Bombyx Mori worms. What makes this silkworm important is that this moth produces a thread that is much smoother, finer and rounder than that of other silkworms. Producing this smooth finer thread consist of two principle stages. First in raising the silkworm and cocoons and second the reeling. To produce high quality of silk the environment needs perfection, preventing the moth from hatching and feeding the silkworm a faultless diet. Eggs need to be kept at 65 degrees with a steady increase to…

sees his wife Miyagi; the twist being she had died previously. When Genjurō wakes up the next morning and sees his wife his missing, an old man comes by and breaks the bad news of her death. That moment was actually a good use of the supernatural in the story. It was a quick moment that helped convey the feelings of forgiveness that Miyagi had for her husband. Lady Wakasa as a plot point just didn’t fit into the otherwise non-supernatural theme of the story. Plot gets a solid 6 out of 10 for…

Carry On My Wayward Son The name the British gave the First World War speaks for itself; the Great War, it sounds like a title to an epic where battle is romanticized.

The reason the British men expected a great war was partly due to the fact that Britain had not been involved in a full-scale war since 1871, and ever since the idea of war had become a mythical journey, where boys became…

Both texts look at the horrors that have derived from conflict including: nature turning against humanity; the loss of civilisation; the loss of faith and the idea of morality. Steven Frye notes that the themes within The Road “deal directly with violence, human degradation, and both human and…

their own. It seems like they have to run from certain things and can’t even defend themselves. However, on TV we are being shown that Americans are winning the war, however we aren’t being shown the difficulties the soldiers are being face with. In conclusion, I believe that this is how going to war actually looks like. The poem is written by Wilfred Owen who served as lieutenant in the war. He has experienced the different situations that going to war brings to people and I believe this poem…
