 FRUITS AND GENERAL HORTICULTURE 



1794. Ardouin-Dttmazet. L'Horticulture des regions devastees. (Horticulture in the 

 devastated regions.) Rev. Hortic. [Paris] 92:61-63. 1920. — A brief statement is given of 

 the general conditions which prevailed in the vicinity of the various centers of horticultural 

 importance, together with an estimate of the damage done by war. The industry is recovering 

 rapidly, since the local demands for the foods produced is as great as formerly, and the diffi- 

 culty and expense of transportation does not permit of securing fruits or vegetables from the 

 southern districts. — E. J. Kraus. 



1795. Aspinwall, B. Planting and cultivating the loganberry. Better Fruit 14 10 : 12. 

 1920. — A brief practical account of planting and cultivating the loganberry. The author is 

 one of the leading loganberry growers of the Northwest. — A. E. Murneek.

1797. Blair, R. E. The work of the Yuma reclamation project experiment farm in 1918. 

 U. S. Dept. Agric. Dept. Circ. 75. 77 p., 32 fig. 1920.— See Bot. Absts. 6, Entry 1406. 



1798. B.rown, W. Robertson. Notes on the progress of the European olive at Peshawar.

1799. Caryl, R. E. The bearing habit of lemons. California Citrograph 5 : 294. Fig. 1-2. 

 1920. — A comparison of the bearing habits of the Eureka and Lisbon, the two chief commer- 

 cial varieties of California. Graphs show comparative pickings for each month in the year at 

 Santa Paula in the cool, moist coast district and at Corona in the hot, dry, interior district. 

 The highest percentage of the Lisbon crop in the Corona district comes in the month of Feb- 

 ruary, while in the Santa Paula district it is one month later. The proportion of midsummer 

 pickings is greater for both varieties near the coast, though there is a greater amount of 

 variation in the Eureka than in the Lisbon. — /. E. Coit. 



1800. Ch asset, L. Determination des fruits (Poires). I. Considerations generales. 

 [Classification of fruits (pears). I. Generalities. Rev. Hortic. [Paris] 92: 106-107. 1920.— 

 Pomological keys have proven unsatisfactory. Most of them are based upon the use to 

 which the fruit is destined, whether for (1) the table, (2) cooking, or (3) cider. These char- 

 acteristics, however, represent a final estimate of the fruit as a whole, and can not be taken as 

 points upon which to construct keys. Nor is it sufficient to attempt classification on the 

 basis of group names such as Doyennes, Bergamotes, Colmars, and the like, since these may 

 contain varieties very different in character. The most satisfactory primary characters are 

 those of shape. (To be continued.) — -E. J. Kraus. 



1801. Ch asset, L. Determination des fruits (Poires). II. La clef pomologique Chasset. 

 [Classification of fruits (pears). II. The Chasset pomological key.] Rev. Hortic. [Paris] 

 92: 126-128. Fig. 33-48. 1920. — A continuation of an article by the same author (Rev. 

 Hortic. [Paris] 92: 106-107. June, 1920). — Three families are created on the basis of the 

 relation of the height of the fruit to its breadth. These are in turn divided into groups accord- 

 ing to the general form of the fruit; each of these forms is designated by a type variety. 

 After a fruit has been placed in its proper family, it is next classified according to its season 

 of maturity; then according to the color of its skin at the time of picking, not at maturity. 

 On the basis of the length and method of insertion of the peduncle, three classes are made. 

 Each of these classes is further divided; first, on the basis of the color of the flesh, and then 

 on its flavor. Farther differentiation of two or more varieties not separated by the above 

 characters is accomplished through reference to descriptive notes. — E. J. Kraus.
