they reach a height of from 12 to 18 ft., after which they begin to siclien and 

 slowly die. The trouble, which may be due to unfavorable soil conditions, is 

 being investigated. Of 20 kinds of eucalypts set out, Eucalyptus rohusta, E. 

 jnperita, E. rostrata, and E. tereticornis are making the most rapid growth and 

 will be used for plantings in low, wet, waste lands. 



Methods for propagating Porto Rican tropical fruits are being studied. Whip 

 grafting young mango seedlings and grafting the Anona cherinwla on a native 

 stock gave promising results. Abcria caffra, Carissa arduina, and Courcoupita 

 guianensis were successfully propagated from cuttings. 



Notes on varieties of tomatoes, C. C. Newman (Sotith Carolina Sta. Bvl. 

 153, pp. 3-30, pis. 8). — Tabular data on a test of over 40 varieties of tomatoes 

 are given, showing for each variety the yield per acre in bushels of both sound 

 and decayed fruit, the time of first ripening and last gathering, the loss in 

 paring, the color, form, relative amount of core, average weight, seed cavity, 

 flavor, average dimensions, and general growth behavior. A brief outline is 

 also given of the manner in which the plants were handled before and after 

 transplanting, together with lists of varieties recommended for early planting 

 and for the general crop. A number of the varieties are illustrated. 



Report of the fruit branch of the Department of Agriculture, Ontario. 1909, 

 P. W. HoDGETTS ET AL. {Rpt. Friiit Branch Dept. Ayr. Ontario, 1909, pp. 112, 

 figs. JfO). — This is the usual report on the work of the fruit branch for 1909 

 (E. S. R., 22, p. 142). An appendix contains a report by T. B. Revett on the 

 conditions of the grape industry in the Niagara district, including a descrip- 

 tion of cultural methods now in vogue. 



The use of sulphate of iron introduced into the trunk or into the branches 

 of fruit trees attacked with chlorosis, J. Coffigniez {Jour. 8oc. Nat. Hart. 

 France, Jf. scr., 11 (1910), Sept., pp. 55Jf-556). — As a result of experiments con- 

 ducted during the past 3 years the author reports that he has successfully 

 combated chlorosis in pear trees by the introduction of sulphate of iron into 

 the wood. 



The operation is performed by preference during the latter part of July. The 

 diameter of the hole is a little less than one-tenth and its depth about one-half 

 of the diameter of the trunk or branch operated upon, and the hole is inclined 

 at an angle of 45° to facilitate the introduction of the sulphate, which should 

 not be put on the bark or on the exterior portion of the sapwood. The sur- 

 face of the hole is refreshed with a pruning knife and covered with grafting 

 wax. 



The author points out that when the chlorosis is due to impoverished soil or 

 when the tree is too old, seriously diseased, or weakened by insects the effect 

 of the sulphate of iron is only temporary. 



The art of grafting and budding, C. Baltet (London, 1910, G. cd., pp. 238, 

 pi. 1, figs. 108). — The present work is a translation of the author's L'Art de 

 Greffer. Various methods of grafting and budding are described at length and 

 the trees, shrubs, etc., to which each mode of operation is best applied are 

 enumerated. The work concludes with practical notes relative to the grafting 

 of about one hundred various kinds of trees and shrubs.
