A Maryland cultivator says that the peach growers of the United States are particularly indebted to Thomas Rivers, for his success in producing an early variety that is intrinsically good.

In the Beatrice we have the result of his hybridizing his very superior Early Silver Peach, with the new White Nectarine, and it is all that the grower can desire in an early Peach, being, though rather small, of beautiful color, agreeable flavor, and a sound, healthy bearer, and possesses remarkable keeping qualities, ripening, whether with Mr. Rivers, under glass, or in this country, where it has been cultivated, fully two weeks earlier than Hale's Early, which has been hitherto regarded as the earliest Peach. He has two other varieties that are second only to the Beatrice, the Early Louise and Early Rivers, both of fine quality, and in ripening follow the Beatrice in the order in which they are named; and both are earlier than Troth's Early, which is usually cultivated as the best early variety. These new varieties of Mr. Rivers' have been imported by some of our enterprising peach-growers, and will furnish the lover of this delicious fruit an opportunity to gratify their taste much earlier in the season than they- could have done but for the skill and enterprise of 'this intelligent orchardist of England.
