In 10(K;, :i2i> seeillings, almost all hybrids, were selected from a larjje plauta- 

 tiou of seetlliug raspberries produced at the statiou and have been planted for 

 further trial. Several of these seedlings are said to be very kirge in size and 

 very productive. Extracts are given from a report on the brambles in the Black 

 Hills made by F. L. Coolv to the South Daliota State Horticultural Society, in 

 which it is stated in substance that blackberries, black-ca)) ras]»berries, and the 

 hybrid rasi)berries of the Columbian type produce on the average only half a 

 crop and are unprofitable commercially. Of a large number of varieties of red 

 raspberries tested in the same region, I^oudon and ^Marlboro are strongly recom- 

 mended for planting, having proven for a number of years moi'e than twice as 

 productive as any others. " Dewberries are productive, but only an expert will 

 be able to make them pay for market." 



The authors are of the opinion that it is useless to expect anything of value 

 from cultivated varieties of raspberries, blackberries, and dewberries upon the 

 open prairies of the Northwest, and that an attempt must be made to cultivate 

 and improve native forms -of these fruits. 



Roselle: Its culture and uses, I*. J. Wester (U. »S'. Dcpt. Agr., Farmers' Bui. 

 301 , />/). 16, figs. 6). — This bulletin deals with the history and geographical dis- 

 tribution of the roselle, together with its botanical characters and relationships, 

 varieties, cultivation and fertilization, yield, harvesting, marketing, composition 

 and uses of the fruit and plant, and notes on breeding, fungus diseases, and 

 insect enemies. 



The roselle is an annual from the Old World tropics. Its iirincipal use is for 

 the making of jellies, jams, etc., from the calyces of the fruit, although the 

 young stems are also said to make good jelly, and the plant is said to be grown 

 in India for its fiber, which is used in the manufacture of cordage and coarser 

 textile products. On account of its extreme sensitiveness to frost it is here 

 recommended for cultivation for its fruit only in tropical and subtropical 

 countries. 



Fruit growers' associations, W. Paddock (Colorado Sta. Bui. 122, pp. 18). — 

 In this bulletin the author describes the workings of the fruit associations in 

 Colorado, including all the important phases of organization methods. A list 

 is given of 33 fruit and produce and cantaloupe associations now doing business 

 in the State. 



As an example of successful cooi)eration a brief history is given of the CJraud 

 .1 unction Fruit Growers' Association, which was started in 1801, and is doing the 

 largest business of any in the State, together with a statement of the business 

 transactetl in 11)00, the by-laws, and the grading list of this association. In 

 1!K»0 a total of l.OoO cars were shipped. The gross receipts were $S14,278.(J2, and 

 the amount paid growers $555,813.44

Investigations on the comparative value of various substances for the 

 preservation of wood, E. Henky [liiil. ^Soc. aSVj. Xaiuy, J. scr., 8 {1907), \o. 1, 

 lip. .'i2-13D, pis. 10). — The author here reports the re.sults of 3 years' experi- 

 ments at the forest .school at Nancy along the above lines, in which a large num- 

 ber of antiseptics were tried on various species of wood used for construction 

 purposes, the object of the experiments being to obtain reliable data for the 

 use of architects, contractors, etc., both with regai-d to the most efficient and 

 economical preservatives and their method of application. 



The author l)riefly reviews the work of other investigators, after which his 

 ex|)eriments, together with the results secured, are discussed in detail. The 

 treated wood has been tested for the 3 years under various conditions, both in
