Maple syrup is a sweet syrup made from maple trees. The sap from the trees is harvested during March. It is then boiled to evaporate water, making it denser and sweeter. It takes roughly 40 litres of maple sap to produce 1 litre of maple syrup. This current process is very similar to that used by the Native Americans except it uses more advanced equipment. According to American Indian legend, the maple trees originally made life free from hardship. They produced a thick syrup all year round which the people would drink. A mythological creature named Glooskap saw that the people of a village were strangely silent. The men were not getting ready to hunt and the women were not minding the fires. He found the villagers sitting near the maple trees letting its syrup drip into their mouth. Glooskap was angered by their laziness and used his powers to fill the trees with water so that they would only produce a dilute, watery sap. This meant that the people had to boil the sap to produce the sweet syrup. Although it wasn't very difficult to do this, it meant that they had to look after their fires and gather firewood. Furthermore, it meant that the trees were not able to produce enough sap to sustain the people all year so they would be forced to hunt and forage during the spring and summer.
