instance, apple grafts of Bechtel's Crab and of Transcendant will compel a far better root 

 system in two years than scions of Baldwin or Yellow Transparent on seedlings of exactly 

 the same grade.— Of all aphis-resistant stocks the Northern Spy is the best. It is largely 

 used in England, South Africa, Australia, and New Zealand. The suggestion is made that 

 the time will probably come when California will use nothing else. In Australia, where 

 woolly aphis is a prolific pest, the nurserymen have developed more than 25 varieties of 

 resistant stocks, but Northern Spy furnishes fully 95 per cent of the apple stock used. — 

 Methods for propagation of the stock are given, which are much like those used for Paradise 

 and Doucin stocks. — /. H. Gourley.

 19: 105. 1920.— All efforts of horticulturists in the West Indies to cultivate the American 

 and European sweet peas { Lathy r us odoratus) have resulted in failure to produce flowers in 

 spite of the vigorous vegetative growth made by the plant. Dr. S. C. Harland at last 

 succeeded in obtaining a single flowering spike after 3 months' growth, from a pink variety 

 of the Spencer type procured from the United States Department of Agriculture. The 

 flowers were very small and without scent. — J. S. Dash.
