1903. Darrow, Geo. M. Are our raspberries derived from American or European species? 

 Jour. Heredity 11:179-184. Fig. 17-20. 1920. — A classification as to species and species 

 crosses of the varieties of raspberries grown in the U. S. A. Classification was made from 

 herbarium material supplemented by field observation and from the history of the variety. 

 Many doubtful cases must be checked up by the plant breeder. A review of material of 

 value to the fruit breeder.— J. H. Beaumont. 



1904. Deming, W. C. Why not develop walnuts, hickory nuts, filberts, butternuts, and 

 chestnuts? Amer. Nut Jour. 11: 23. 1919. 



1905. Drieberg, C. A freak pawpaw (Carica Papaya). Jour. Heredity 10:207. 1919. — 

 Trees found in Ceylon bearing sulphur yellow fruits, the smaller fruits being almost white. 

 Seeds in part bred true, in part gave rise to trees bearing the ordinary green fruits. — J. R. 

 Schramm. 



1906. Edwards, C. L. Lessons of the season. Amer. Nut Jour. 11: 94, 1919. — Empha- 

 sizes proper drainage for pecan trees. — -E. L. Overholser. 



1907. Edwards, C. L. Official report on nut growing in Texas. Amer. Nut Jour. 11: 95, 

 97. 1919. 



1908. Fletcher, S. W. Observation on French horticulture. Proc. Amer. Soc. Hort. Sci. 

 16:136-140. (1919) 1920.— Information is given concerning the amount and character of 

 horticulture in France. As compared to America's extensive plantings and commercial 

 orchards, fruit and vegetable growing is more intensive in France. Likewise there is a much 

 keener interest in amateur horticulture. More dwarf trees are used and they are very care- 

 fully trained into various shapes and patterns. — E. C. Auchter. 



1909. Gallard, L. Strawberry culture around Sydney. Agric. Gaz. New South Wales 

 31:731-737, 815-820. 10 fig. 1920. — Popular description of methods is given, including 

 method and time of planting, varieties, mulching, treatment of runners, harvesting and 

 irrigation, along with other details. — L. R. Waldron. 



1910. Galloway, Beverly T. Some promising new pear stocks. Jour. Heredity 11: 

 25-32. Fig. 10-17. 1920.— About five million pear trees must be grown each year to meet the 

 losses caused by fire-blight and normal orchard increase. The Office of Foreign Seed and 

 Plant Introduction, U. S. A., has introduced a large number of pears and during the last few 

 years has given considerable attention to testing them for stock breeding purposes and for 

 fruit. The office highly recommends the Chinese Calleryana pear as the most rapid growing, 

 most easily budded, and most resistant of any stock. Several others of these Chinese impor- 

 tations are much superior to the French stock that is now used. — /. H. Beaumont. 



1911. GuiLLATJMiN, A. Citranges, limonanges, satsumanges. Eev. Hort. 92:140-142. 

 Fig. 60-51. 1920. — Hybrids between Citrus trifoliata and the various subspecies of Citrus 

 Aurantium, known as citranges, have been secured by Trabut in Algiers, Bernard at Mon- 

 tauban, and Webber and Swingle in Florida. Among these the two varieties Armand Ber- 

 nard and Rusk are best known. A second lot of seedlings was obtained by Bernard by cross- 

 ing several varieties of oranges with C. trifoliata. These are distinct from the other type of 

 citrange and are designated as Citrange de Montauban ameliore. The fruits of at least two 

 forms are edible. (To be continued.) — E. J. Kraus. 



1912. Hatton, Ronald G. A first report on quince stocks for pears. Jour. Roy. Hort. 

 Soc. 45: 269-277. Fig. 62-66. 1919.— Beginning in 1914 a collection of quince stocks used for 

 pear propagation has been acquired from various English and foreign nurserymen at the Wye 

 College Fruit Experiment Station. Out of this collection five chief groups or types have 

 been distinguished and their botanical and horticultural character described and illustrated. 

 Their probable identifications are A. d'Angers, B. Common, C. Unknown, D. de Fontenay and
