839. Thomas, Owen. Forgotten or discarded grapes. Jour. Pomol. 1: 161-165. 1920.- 

 The author discusses the quality and characters of a number of varieties of grapes, especially 

 those grown in England about 1830. — L. H. MacDaniels. 



840. Wellington, Richard. Grape varieties that produce seedlings of superior merit. 

 Proc. Amer. Soc. Hort. Sci. 17: 37-40. 1920 [1921].— The report deals with about 11,000 grape 

 seedlings grown at the New York Agricultural Experiment Station, and obtained from -37 

 variety crosses, 38 varieties by seedling crosses, 9 seedling crosses, 163 variety self-fertiliza- 

 tions, 50 seedling self-fertilizations, and a few species crosses. The number of plants in each 

 cross or self-fertilization varied from 1 to over 500. — The author concludes that only 1 individ- 

 ual out of each 1000 will be worthy of perpetuating. The crosses gave proportionately more 

 desirable seedlings than the selfed varieties. Most of the varieties used proved to be poor 

 parents but a few produced a remarkably large number of excellent seedlings. A table is 

 included of the variety crosses and selfed varieties, showing the percentage and number of 

 vines set and number and per cent selected for propagation. The most desirable crosses 

 are Governor Ross X Mills, Mills X (Winchess X Diamond) . Triumph X Mills, and Winchell 

 X Diamond. Mills has been the leading grape for producing high quality. Diamond pro- 

 duced good quality and Winchell proved of exceptional value in introducing earliness without 

 impairing quality. The author concludes that to produce desirable seedling grapes, Vitis 

 vinifera species or derivatives of this species must be depended on for quality and V. labrusca, 

 V. vuljnna, and other American species for hardiness. More certain results will be obtained 

 by crossing rather than selfing and in using varieties that are known to produce superior 

 progeny. — H. W. Richey.

 Pest and Hort. Rept. 3: 49-51. 1921. — Applications of oj-S lbs. of nitrate of soda to the 

 soil under each of a number of old Italian prune trees 1 month before blooming resulted in 

 increased growth and increased number and size of fruits. The time required to dry the fruit 

 was not increased. Applications of the same material at the rate of 250 lbs. per acre to red 

 raspberries at the time the new canes were about 3 inches tall resulted in more and larger 

 canes per plant, and an increased yield of fruits of larger size and better color. There was 

 severe killing of the new canes, which continued to grow into the fall and winter. — E. J,

FLORICULTURE AND ORNAMENTAL HORTICULTURE 



843. AusT, F. A. A state program for landscape extension. Proc. Amer. Soc. Hort. Sci. 

 17: 54-60. 1920 [1921]. — The relation of landscape extension to the sciences is briery touched 

 upon. Man's need for natural beauty, and the usefulness and beauty of his natural surround- 

 ings are discussed. Landscape extension is defined as "The development of the appreciation 

 and the furthering of the practice of the fundamental principles of the art of landscape design, 

 by the citi/ens of every community." The designer must study the life about him in order to 

 interpret it to the community which he serves. His duty is to teach the public the best in 

 landscape art and to demonstrate the value of professional assistance. "The main function 

 of landscape extension is education." The leaders must cooperate with existing organiza- 

 tions and agencies in order to avoid du7)lication of effort. The extension program should in- 

 clude: (1) Research in landscape problems, (2) demonstration, (3) lecture work, (4) publica- 

 tion, (5) follow-up work. Types of demonstrational work found effective in Wisconsin are 

 listed and the paper closes with a discussion of the state extension program. — W. R. Ballard.
