suminor jK-ars at the sul)station, and appt-arK to be sutliciently resistant to ))liglit to 

 enalile it to proiliUH- <:oo(l crops durint,' most of the season. A variety of fi}^ known as 

 " Wliile Dattato" is considered tlie Ix'st white flj^ jrrow ii at the station. Nearly all 

 varieties of <rrapes have done well at this snhstation. 



Testing varieties of vegetables, ('. 11. P.kkwer (Avier. Agr., 7-? [1904), Xo. f!, 

 p. i.;,').— As a result of a test of a nunilHT of varieties of ve<retaV<les the author 

 reeoninieuds Sparks Earliana tomato, New White p]vergreen corn, and Stringless 

 Green Pod, J?rittle Wax, and AVardwell Wax beans. 



Treating trees that have been injured by mice or rabbits, N. O. 1'.ooth 

 [Xeir York- Stair ,St<i. Rpt. 1902, pp. 401-404)- — This is a reprintof a circular issued l)y 

 the station, and gives directions for treatment of trees that have l)een more or less 

 seriously injured by the gnawing off of the bark Ijy mice and rabbits. ^Methods of 

 bridge grafting to overcome these injuries are described. 



Irrigating oranges, A. J. IIi'tchixsox {Parifir Fruit World, 17 {1904), No. IS, 

 pp. 4, 0). — The author notes that under the influence of abundant irrigation the size 

 of oranges is becoming larger, and the fruit coarser and inferior in quality. As a 

 remedy for this he advises the application of water to the trees just at the time a new 

 growth is starting out from the buds. By the application of a sufficient amount of 

 wati-r at this time the new growth can be carried to a good maturity and desirable 

 length. If irrigation is delayed until after the growth has acquired consideral)le 

 length, then that growth that has already started is merely lengthened without pro- 

 ducing any more fruit-])earing wood. 



Examination of sugar, prunes (Burbank) from several localities, (i. E. 

 Coi.HV {Calij'oniiu <S7'7. Jijit. 1902-3, pi>. 90, 91). — Analyses, chiefly with reference to 

 size, percentage of flesh, pits, and total sugar content are given for a number of sugar 

 prunes and other prunes grown in different localities in California. The sugar con- 

 tent of the sugar prunes in the fresh fruit varied from 13.7 to 20.53 per cent, and the 

 average sugar content of California French prunes is given as 18.5 per cent. In the 

 dried product the sugar content of the sugar jirmies was found to be 49.5 to 50 per 

 cent, and the maximum sugar content in dried French prunes 54 \wr cent. 



Review of preliminary work at [Cranberry] experimental station, II. A. 

 Ka.msev (Cnuiberrij Grover, 2 {1904), No. 2, pp. 2, 3). — Herewith is given a rather 

 detailed account of the experimental plats and methods of treatment in the work on 

 cranberry culture, carried out under the auspices of the University of Wisconsin. 

 An experiment w'as made to determine the effect of stretching cheese cloth about 2 

 ft. above the vines for the prevention of blight. The cloth, however, was not put in 

 place soon enough and some of the vines had already begun to blight. The berries 

 continued to blight, however, under the cheese cloth, which seemed to indicate to 

 the author that all blight is not caused by intense heat in the presence of water. 



Tests are being made of 187 varieties which have thus far been originated, and 

 continued efforts are being made to secure more valuable varieties by cross fertilizing. 



Viticulture, E. II. Twight {California ,Sta. Rpt. 1902-3, pp. 111-113) .—Thin is an 

 outline of the viticultural work that is now being carried on under the auspices of 

 the station. A numl)er < f experimental plats have been established in different 

 parts of the State, chiefly for the purpose of determining the adaptation of phylloxera- 

 resistant stocks to the different soils of California. Two plats established in coopera- 

 tion with this Department will be used to determine questions of adaptation, but 

 mainly for testing the affinity of vinifera scions to resistant stocks. It is reported 

 that the phylloxera is spreading throughout California, and planters are urged to use 

 only resistant stocks in setting out new vineyards. 



Attention is called to the serious character of the Anaheim disease, which has been 

 located in at least 3 important vine-growing districts. The use of cuttings from 

 infected districts is condemned.
