LUTHER BURBANK: AND HIS HORTICULTURAL CREATIONS. 83 
new and greatly improved varieties of quinces, walnuts, chestnuts, gladioli, 
callas, clematis, nicotianas, lilies, roses, blackberries, raspberries and many 
other plants. One of Mr. Burbank’s latest and most valuable productions 
is an apricot-plum hybrid, which is a large smooth-skin, free-stone fruit of 
excellent quality. 
By crossing the small stoneless Damson plum with the French prune 
he has produced a large number of stoneless plums of good size and qual- 
ity. In a few cases some of these varieties have remnants of stone left on 
one side of the seed, that were perhaps as big and thick as the finger nail 
of my little finger. The seed, however, was generally well developed, al- 
though in a few cases this, too, had become nearly or quite obliterated, and 
one seedless and stoneless variety is extremely early. Some of these plums 
are of large size, and it would seem that they must be the precursors of 
marketable pitless plums. 
Common Field Daisy. Showing’ five large blooms of the improved form, 5% inches in 
diameter, and of graceful forms; and below the common field daily without improvement. 
He has one plum tree which he said produced pistillate flowers only, 
and these have no petals. Another plum tree has flowers that never open, 
yet it fruits abundantly, the flowers, unquestionably, being self-fertilizing in 
the bud. In peaches he has got some of his best results by crossing the 
Alexander and Wager peach with the white nectarine. He has crossed the 
peach and almond. 
He has been paying considerable attention lately to the improvement 
of the common field daisy, or whiteweed of the eastern states (Chrysanthe- 
mum lecanthemum), and has obtained flowers five and one-half inches in 
diameter and of most graceful forms, thus making it an interesting and
