Build a Better House - With Dirt

Build a Better House - With Dirt Tomorrows homes may be made of glass and steel- or they may resemble the shelters built by our prehistoric ancestors. Architects and engineers are taking a new look at ancient building techniques, including building with earth products. Imagine a magical building material. Its cheap, perhaps even free. Its plentiful everywhere, worldwide. Its strong enough to hold up under extreme weather conditions. Its inexpensive to heat and cool. And its so easy to use that workers can learn the necessary skills in a few hours. This miraculous substance isnt only cheap as dirt, it is dirt, and its winning new respect from architects, engineers, and designers. One look at the Great Wall of China will tell you how durable earthen construction can be. And, concerns for the environment and energy conservation make ordinary dirt look downright appealing. What does an earth house look like? Perhaps it will resemble the 400-year-old Taos Pueblo. Or, tomorrows earth homes may take on surprising new forms. Types of Earth Construction An earth house can be made in a variety of ways: AdobeRammed EarthCob (mud with straw)Compressed Earth BlocksStraw Bale (not really earth, but very organic) Or, the house may be made with concrete but earth sheltered underground . Learning the Craft How many people live or work in buildings constructed of earth? The folks at eartharchitecture.org estimate that 50% of the worlds population spend much of their time in earthen architecture. In a global market economy, its time that more developed nations take note of this statistic. Traditional adobe homes in the American Southwest have wooden beams and flat roofs, but Simone Swan and her students at the Adobe Alliance have discovered the African mode of construction, with arches and domes. The result? Beautiful, ultra-strong, and energy-efficient homes, echoing the adobe domes built along the Nile centuries ago and being built today like earth igloos in places like Namibie and Ghana in Africa. No one can argue with the environmental benefits of using mud and straw. But the ecological building movement does have critics. In an interview with The Independent, Patrick Hannay, from the Welsh School of Architecture, attacked the straw bale structures at the Centre for Alternative Technology in Wales. There would appear to be little aesthetic leadership here, Hannay said. But, you be the judge. Does responsible architecture have to be unsightly? Can a cob, straw bale, or earth sheltered home be attractive and comfortable? Would you like to live in one? Designing a More Beautiful Mud Hut The African earth igloos, however, come with a stigma. Because of primitive construction methods, mud huts have been associated with housing for the poor, even if building with mud is a proven architecture. The Nka Foundation is trying to change the mud hut image with an international competition. Nka, an African word for artistry, challenges designers to give these ancient building practices a modern aesthetic that is missing. The challenge outlined by the Nka Foundation is this: The challenge is to design a single-family unit of about 30 x 40 feet on a plot of 60 x 60 feet to be built by maximum use of earth and local labor in the Ashanti Region of Ghana. The client of your design is the middle-income family in any township of your choice in the Ashanti Region. Total costs of constructing the design entry must not exceed $6,000; land value is excluded from this price point. The entry should serve as an example to the local people that mud architecture can be beautiful and durable. The need for this competition tells us several things: How something is built can have little to do with aesthetics. A home can be well-made but ugly.Attaining status through architecture is nothing new; creating an image transcends socio-economic class. Design and construction materials, the essential tools of architecture, have the power to make or break stigma. Architecture has a long history of design principles that often get lost through the years. Roman architect Vitruvius set a standard with 3 Rules of Architecture- Firmness, Commodity, and Delight. Heres hoping that earth igloo construction will rise to the level of being built with more beauty and delight.

American Revolution - Treaty of Alliance (1778)

American Revolution - Treaty of Alliance (1778) The Treaty of Alliance (1778) between the United State and France was signed February 6, 1778. Concluded between the government of King Louis XVI and the Second Continental Congress, the treaty proved critical to the United States winning its independence from Great Britain. Intended as a defensive alliance, it saw France provide both supplies and troops to the Americans while also mounting campaigns against other British colonies. The alliance continued after the American Revolution but effectively ended with the start of the French Revolution in 1789. Relations between the two nations deteriorated in the 1790s and led to the undeclared Quasi-War. This conflict was ended by the Treaty of Mortefontaine in 1800 which also formally terminated the 1778 Treaty of Alliance. Background As the American Revolution progressed, it became obvious to the Continental Congress that foreign aid and alliances would be necessary to achieve victory. In the wake of the Declaration of Independence in July 1776, a template was created for potential commercial treaties with France and Spain. Based on the ideals of free and reciprocal trade, this Model Treaty was approved by Congress on September 17, 1776. The following day, Congress appointed a group of commissioners, led by Benjamin Franklin, and dispatched them to France to negotiate an agreement. It was thought that France would prove a likely ally as it had been seeking revenge for its defeat in the Seven Years War thirteen years earlier. While not initially tasked with requesting direct military assistance, the commission received orders instructing it to seek most favored nation trading status as well as military aid and supplies. Additionally, they were to reassure Spanish officials in Paris that the colonies had no designs on Spanish lands in the Americas.   Treaty of Alliance (1778) Conflict: American Revolution (1775-1783)Nations Involved: United States and FranceSigned: February 6, 1778Ended: September 30, 1800 by the Treaty of MortefontaineEffects: The alliance with France proved critical to the United States winning its independence from Great Britain. FReception in France Pleased with the Declaration of Independence and the recent American victory at the Siege of Boston, the French Foreign Minister, Comte de Vergennes, was initially in support of a full alliance with the rebelling colonies. This quickly cooled following General George Washingtons defeat at Long Island, the loss of New York City, and subsequent losses at White Plains and Fort Washington that summer and fall. Arriving in Paris, Franklin was warmly received by the French aristocracy and became popular in influential social circles. Seen as a representative of republican simplicity and honesty, Franklin worked to bolster the American cause behind the scenes. Benjamin Franklin in Paris. Public Domain Aid to the Americans Franklins arrival was noted by the government of King Louis XVI, but despite the kings interest in assisting the Americans, the countrys financial and diplomatic situations precluded providing outright military aid. An effective diplomat, Franklin was able to work through back channels to open a stream of covert aid from France to America, as well as began recruiting officers, such as the Marquis de Lafayette and Baron Friedrich Wilhelm von Steuben. He also succeeded in obtaining critical loans to aid in financing the war effort. Despite French reservations, talks regarding an alliance progressed. The French Convinced Vacillating over an alliance with the Americans, Vergennes spent much of 1777 working to secure an alliance with Spain. In doing so, he eased Spains concerns over American intentions regarding Spanish lands in the Americas. Following the American victory at the Battle of Saratoga in the fall of 1777, and concerned about secret British peace overtures to the Americans, Vergennes and Louis XVI elected to forego waiting for Spanish support and offered Franklin an official military alliance.

In addition, the men signed the Franco-American Treaty of Amity and Commerce which was largely based on the Model Treaty. The Treaty of Alliance (1778) was a defensive agreement stating that France would ally with the United States if the former went to war with Britain. In the case of war, the two nations would work together to defeat the common foe. The treaty also set forth land claims for after the conflict and essentially granted the United States all territory conquered in North America while France would retain those lands and islands captured in the Caribbean and Gulf of Mexico. In regard to ending the conflict, the treaty dictated that neither side would make peace without the consent of the other and that the United States independence would be recognized by Britain. An article was also included stipulating that additional nations may join the alliance in the hope that Spain would enter the war. Effects of the Treaty On March 13, 1778, the French government informed London that they had formally recognized the independence of the United States and had concluded the Treaties of Alliance and Amity and Commerce. Four days later, Britain declared war on France formally activating the alliance. Spain would enter the war in June 1779 after concluding the Treaty of Aranjuez with France. The entry of France into the war proved a key turning point in the conflict. French arms and supplies began to flow across the Atlantic to the Americans. In addition, the threat posed by the French military forced Britain to redeploy forces from North America to defend other parts of the empire including critical economic colonies in the West Indies. As a result, the scope of British action in North America was limited. Though initial Franco-American operations at Newport, RI and Savannah, GA proved unsuccessful, the arrival of a French army in 1780, led by Comte de Rochambeau, would prove key to the wars final campaign. Supported by Rear Admiral Comte de Grasses French fleet which defeated the British at the Battle of the Chesapeake, Washington and Rochambeau moved south from New York in September 1781.

Cornwallis surrender effectively ended the fighting in North America. During 1782, relations between the allies became strained as the British began pressing for peace. Though largely negotiating independently, the Americans concluded the Treaty of Paris in 1783 which ended the war between Britain and the United States. In accordance with the Treaty of Alliance, this peace agreement was first reviewed and approved by the French. Nullification of the Alliance With the end of the war, people in the United States began to question the duration of the treaty as no end date to the alliance was stipulated. While some, such as Secretary of the Treasury Alexander Hamilton, believed that the outbreak of the French Revolution in 1789 ended the agreement, others, such as Secretary of State Thomas Jefferson, believed that it remained in effect. With the execution of Louis XVI in 1793, most European leaders agreed that treaties with France were null and void. Despite this, Jefferson believed the treaty to be valid and was backed by President Washington. As the Wars of the French Revolution began to consume Europe, Washingtons Proclamation of Neutrality and the subsequent Neutrality Act of 1794 eliminated many of the treatys military provisions. Franco-American relations began a steady decline which was worsened by the 1794 Jay Treaty between the United States and Britain. This began several years of diplomatic incidents which culminated with the undeclared Quasi-War of 1798-1800.

As part of the conflict, Congress rescinded all treaties with France on July 7, 1798. Two years later,  William Vans Murray, Oliver Ellsworth, and William Richardson Davie were dispatched to France to commence peace talks. These efforts resulted in the Treaty of Mortefontaine (Convention of 1800) on September 30, 1800 which ended the conflict. This agreement officially ended the alliance created by the 1778 treaty.
