The hemlock woolly adelgid Adelges tsugae , an exotic aphid-like insect, has become a serious threat to the eastern hemlock. These insects feed on the sap of the youngest branches of hemlock, where the needles attach to the twig. The adelgids inject a toxic saliva into the plant as they feed, killing existing needles and interfering with the tree's ability to produce new ones. If it is not controlled, the infected trees may die in three to four years. This would greatly alter the composition and function of hemlock-hardwood swamps.

Cicuta , commonly known as water hemlock , is a genus of four species of highly poisonous plants in the family Apiaceae. They are perennial herbaceous plants which grow up to 2. Plants in this genus may also be referred to as cowbane or poison parsnip.

Since the dawn of history, humans have made great use of leather. Turning animal skin into a durable product requires processing, and in primitive times, hides were tanned using animal brains, dung, urine, ash, and smoke. As our understanding of chemistry evolved, these materials were replaced by vegetable, mineral, and then nonorganic ingredients. Today, synthetic materials have replaced leather in many shoes and boots; nylon and reinforced cotton have replaced leather in coats; and a cow hide is more likely to become gelatin than it is a saddle. All of this can make it hard to remember that at one time the manufacturing of leather goods was an economic engine sustaining many communities in the northeastern United States. This story played out across the Northeast and helped shape the forest that we know today. The tanning process In colonial America, the creation of leather from animal skins was a crucial part of life. Back then, almost every farm and homestead prepared its own leather from slaughtered domestic or wild animals.
