This native laurel, lover of rich, moist soil, deserves the place in cultivation more commonly granted its European cousin, _Laurus nobilis_, Linn., the familiar tub laurel of hotel verandas in the Northern states, and much grown out of doors in southern California and in milder climates east. The tree is occasionally sixty to seventy feet high, with trunk two to three feet in diameter. Such specimens furnish the cabinet-maker and carpenter with a beautiful, bright red, close-grained wood for fine interior finish and furniture. Formerly it was used in the construction of river boats, but the timber supply is now very limited.
In Florida and southern California the avocado or alligator pear is being extensively cultivated. This laurel grows wild in the West Indies, Brazil, Peru, and Mexico. Its berry attains the size of a large pear. It has been developed in several commercial varieties, all having smooth green or purple skin, and soft oily pulp like marrow surrounding a single gigantic seed. It is usually cut in two like a melon and eaten raw as a salad dressed with vinegar, salt, and pepper. Once a stranger acquires the taste, he is extremely fond of this new salad fruit. The growing of the trees is easy and very profitable. At present the fruits are in great demand in city markets, and the prices are too high for any but the rich to enjoy this luxury.
Where a market is difficult to reach, the abundant oil is expressed from these fruits and used for illumination and the manufacture of soap. The seeds yield an indelible ink.
It is interesting to the student of trees to note how many tropical families have representation in North America, due to the fact that Florida extends into the tropics, and the West Indies seem to form a sort of bridge over which Central American and South American species have reached the Floridian Keys and the mainland.
The sole remnant of an ancient genus is the aromatic sassafras familiar as a roadside tree that flames in autumn with the star gum and the swamp maples. In the deep woods it reaches a height of more than a hundred feet and is an important lumber tree. In the arctic regions and in the rocky strata of our western mountains, fossil leaves of sassafras are preserved, and the same traces are found in Europe, giving to the geologist proofs that the genus once had a much wider range than now. But no living representative of the genus was known outside of eastern North America, until the report of a recently discovered sassafras in China.
