This is certainly a very remarkable variety, which is rapidly gaining favor in localities where the Antwerps fail. Fruit medium to large, globular, dark reddish purple, moderately firm, subacid, and second rate in quality.
The above may appear to be a poor recommend to a variety which we have called remarkable, and it certainly would be if it possessed no other merit except that of size and quality of the fruit. But the excellence of the Philadelphia consists in its great productiveness, hardiness of the plant, vigorous growth, tough and enduring leaves, rendering it capable of withstanding the hot, scorching weather of August even in the Middle and Southern States, where many other kinds utterly fail.
Those who plant the Philadelphia Raspberry are very sure of getting a bountiful crop, even if it is not so exquisite in flavor as the Orange or Fastolff.

The Hildreth is another variety; the fruit is of most excellent quality, but rather soft for transportation.
