Narrative
This discovery is a new variety of thornless Logan blackberry having large, strong and relatively nonbrittle canes, the fruit of which is larger than, but similar as to color and taste to the fruit of the Logan blackberry from which this new variety has been propagated. Also this new variety is further distinguished from the parent variety in the respect that it bears longer and is more prolific. This new variety was discovered by us as a sport that was growing from a cane of a Logan blackberry plant and from its first appearance indicated an individual variation from the parent stock or cane in the respect that it was thornless.This sport was discovered in our garden in the city of San Gabriel, county of Los Angeles, and State of California, growing on one of the plants of a row of Logan blackberries, and immediately after this discovery we held a consultation, and concluded to begin a propagation of this sport to see if it would retain permanently its thornless character.This propagation included cutting away at once the thorny portion of the parent Logan blackberry plant and all the roots thereof, except that to which the sport was directly connected. This sport was then cultivated until it grew to the usual length and spread of an ordinary Logan blackberry plant, and at the proper time, in September 1930, we laid the tips of this thornless cane in the ground to develop a new variety which, when developed and replanted in the spring of 1931, grew into thornless plants, some of which bore fruit that year which, as to size, color and taste resembled the fruit of the parent plant, except that its fruiting period began much earlier than Logan blackberries growing in the same garden under like conditions, and continued in full fruitage much longer than the Logan blackberries.In September of 1931 we again laid the tips of the thornless canes developed from the thornless sport which we discovered, and in the spring of 1932 we planted and cultivated the plants developed by the 1931 tipping; and all of these plants grew true to the sport in the respect that they are entirely thornless, and from this development we are assured that the thornless characteristic of this new variety is permanent.In the accompanying drawing the new variety of Logan blackberry, together with its fruit and foliage is illustrated, which illustration was made by the artist from cuttings taken from plants growing In our garden showing the parent Logan blackberry cane and also a cane of the new variety.
