The reconstruction of vineyards without grafting, C. Oberlin {Weinbau u. 

 Weinfiandel, 31 {1913), Nos. 28, pp. 287, 288; 20, p. 207; 30, pp. 307, 308; 31, 

 pp. 317, 318; 32, pp. 327, 328; 33, pp. 337, 338; 34, p. 3^7).— After a general 

 survey of the results secured in reconstituting phylloxera infested vineyards in 

 Europe the author concludes in substance tliat, although the use of American 

 grape stocks may be the best means of reconstituting the vineyards in the 

 warmer parts of Europe, the use of grafted vines is too costly and complicated 

 a process for cold climate regions such as Alsace-Lorraine, where it is necessary 

 to plant the grape sufficiently deep to protect the grafts from frosts. He calls 

 attention to the relative resistance of grapes grown by the cordon system to 

 phylloxera as compared with grapes grown on individual stakes, as well as the 

 greater ease with which cultural and spraying treatments may be given. With 

 special reference to the industry in Alsace-Lorraine he suggests that the double 

 arm cordon system be adopted and attention also given to the testing of direct- 

 bearing American-European hybrids which are much more frost resistant than 

 the grafted stocks. 



Some new or little-known Philippine economics, O. W. Barrett {Philippine 

 Agr. Rev. [EngUsJi Ed.], 6 {1013), No. 10, pp. 403-503, pis. 10). — Brief descrip- 

 tions are given of a large number of native fruits and plants of more or less 

 economic importance. 



The Kafir orange, D. Fairchild {Amer. Breeders Mag., 4 {1013), No. 3, 

 pp. 148-153, figs. 2). — Attention is here called to the Kafir orange {Strychnos 

 spinosa), an edible member of the strychnin producing genus which has been 

 successfully grown in Florida and southern California. Notes are also given 

 on other species of this genus which promise to succeed in our semitropical 

 regions and which with a little improvement through hybridization and selec- 

 tion may offer a number of unique fruits to American growers. 



American medicinal flowers, fruits, and seeds, Alice Henkel (17. /sf. Dept. 

 Agr. Bill. 26, pp. 16, figs. 12). — This bulletin describes the following 13 plants, 

 the flowers, fruits, or seeds of which are in greatest demand for medicinal pur- 

 poses: Juniper {Juniperus communis), saw palmetto {Screnoa scrrulata), 

 wormseed {Chenopodiiim antlielminticuiiv) , pokeweed {Phytolacca americana), 

 black mustard {Brassica nigra), white mustard {Sinapis alha), raspberries 

 {Ruhiis occidentalis and R. st7-igosiis), prickly ash {Zanthoxylum americanum 

 and Z. clava^hermUis) , smooth sumac {Rhus glabra), American linden {Tilia 

 americana), poison hemlock {Conium maculatum), jimson weed {Datura stra- 

 monium,), mullein {Verbasaim thapsus), and elder {Samhucus canadensis). 



Each plant is discussed with reference to its sjTionymy, habitat and range, 

 description, collection, uses, and prices. Brief suggestions are given relative to 

 the collection of flowers, fruits, and seeds. 



Experiments in bulb growing at the United States Bulb Garden at Bel- 

 lingham, P. H. Dorsett {U. S. Dept. Agr. Bui. 28, pp. 21, figs. 21) —In 1908 

 the Bureau of Plant Industry established an experimental bulb garden at Bel- 

 lingham, Wash., to determine the feasibility of growing the so-called *' Dutch 

 bulbs," including hyacinths, narcissuses, and tulips in the United States. This 

 bulletin reports the progress and present status of the work, including the cul- 

 tural practices thus far employed. 



Generally speaking the results have been satisfactory, a high grade of bulbs 

 having been produced. On the other hand, the Department is not prepared to 

 recommend the commercial culture of " Dutch bulbs " in this country until fur- 

 ther information is gained relative to climatic and soil requirements, cultural 

 practices, and methods of harvesting, curing, storing, transporting, and mar- 

 keting the crop.
