It also describes a root which grows sometimes as large as a human head; this must have been what is now known as the tanger. But the greatest discovery of all was the potato, which has been of such inestimable benefit to mankind. This, which they carried home, was cultivated by Raleigh, on his estate in Ireland, and thence disseminated through Europe.

Scarcely any part of our country has a greater variety of plants and trees than this vicinity. It will be found an interesting field for botanists.
Only a few days had elapsed after the departure of the colonists, when a ship, prepared and furnished with supplies from Raleigh, arrived at Roanoke. After some days spent by her commander in searching for his countrymen, he set sail for home.

He, however, made extensive explorations, and leaving fifteen men to reside at Roanoke and keep possession of the country, departed for home. One would suppose that Raleigh, by this time, would have become disheartened by his disappointments in
