New citrus and pineapple productions of the Department of Agriculture, 

 H. J. Webbeb {U. S. Dept. Agr. Yearhook 1906, pp. 329-346. pis. 8, fig. i).— De- 

 scriptions and illustrations are given of 3 new citranges, the Colman, Savage, 

 and Rustic, a new loose-skinned orange, the Thornton, and 7 new pineapples 

 originated under the direction of the author, and named as follows : Deliciosa, 

 Dade, Coquina, Jupiter, Orlando, Jensen, and Biscayne. 



The citranges are sister fruits of the Willits and Morton. The Colman is the 

 only citrange thus far secured which has inherited in any marked degree the 

 fuzzy character of the Trifoliate orange. It is practically seedless and very 

 juicy. The Savage appears to be the most fruitful of all the citranges aside 

 from the Rusk. While the fruit of the Rustic is not considered so good as 

 that of the Colman and Savage it produces a bushy, low-growing tree, which 

 it is believed will render it specially desirable for cultivation as a lawn tree or 

 a hedge plant. 



With regard to the methods of propagating the citrange varieties, the writer 

 advises that they be budded on 2 or 3 year old seedlings of the Trifoliate 

 orange, and again emphasizes the statement that the citranges must not be 

 confounded with oranges, but are principally of value for culinary purposes 

 and for making citrangeade, for which purpose they are highly recommended. 



The new loose-skinned orange, the Thornton, is believed to have originated 

 as a hybrid between the pomelo and tangerine, from which cross the tangelo 

 was also produced. As compared with the tangelo, however, the Thornton is 

 sweet and not l)itter. reseml)ling an orange more than a pomelo, and from its 

 general characteristics would be classed as a loose-skinned common orange, 

 while the tangelo may be described in general as a loose-ski une^ pomelo. 



The new pineapple hybrids, of which 6 have smooth-margined leaves, are also 

 described in detail. 



pineapple growing in Jamaica, G. L. Lucas (BuI. Dept. Agr. [■/mnaica], 

 5 (1907), No. 2-3. pp. .'//-'/.?). — In this article the author states that the cause 

 of the repeated failure of pineapple growing in Jamaica can be attributed to a 

 persistency in ignoring the Red Spanish, generally considered the one profitable 

 and marketable pineapple, and which variety constitutes 00 per cent of all the 

 pineapples grown in coiintries where the business is successful. 



The olive, L. Degrully {UOUvier. Montpellier: Coulet & Sons; Paris: Mas- 

 son d Co., 1907, pp. 223, figs. .9//). — This is a treatise on olive culture. The 

 work is introduced by a botanical study of the olive, written by C. Flahault 

 and formerly published in the annals of the Montpellier National School of 

 Agriculture, 1886. Part 2 is devoted to varieties of olives grown in France, 

 Algeria, Tunis, Italy, and Spain, including the various synonyms, and descrip- 

 tions of tree and fruit, with notes on the varieties described. This is followed 

 by directions for the cultivation of olives, including soils, methods of propaga- 

 tion, planting, pruning, irrigation, fertilizing, and harvesting. Part 4 consists of 

 descriptions of the various insects and fungus diseases attacking the olive, with 

 suggestions for their control. 



Olives and olive oil, A. B. Butman (Mo. Consular and Trade Rpts. [V. 8.], 

 1907, No. '320, pp. 195-198). — This is a brief report on the cultivation of olives 

 and their conversion into oil in Italy. It is estimated that fully 2,000,000 

 acres of land are devoted to olive culture, with an annual average yield of 

 75,000,000 gal. of oil. 



The fermentation of tea, II, H. H. Mann (Indian Tea Assoc. [Pamphlet] 

 1. 1907, pp. 17). — In Part I of this report, which appeared in April, 1906 (E. S. 

 R., 18, p. 42), an account was given of the effect of changes of temperature and 

 thickness of spreading on the leaf, and of the period of fermentation on the 

 process of tea fermentation with relation to the influence of these factors on
