ing those reported in 1903. On the strength of these experiments Kubanka

HORTICULTURE. 



Studies in plant breeding in the Tropics, R. H. Lock {Ann. Roy. Bot. Gard. 

 Peradeniya, 2 (190',), ^'u. 2. pi). 299-356; {1905), No. 3, pp. 5.57W,i ', ).— The 

 author gives brief historical notes on the general subject of plant breeding, 

 giving special attention to the results secured by ]\Iendel and the confirmation 

 of these by more recent experimenters. 



Details are also given of a large amount of the oxperiuiental work by the 

 author in crossing various cultivated peas with native jx'as. Tlie results 

 obtained in these experiments are in the main contirmatory of those secured l)y 

 Mendel, although several exceptions occurred. A bibliography of SO papers on 

 various phases of i)lant breeding is included. 



Truth about ginseng culture, W. M. Evans {Rural New Yorker, 65 {1906), 

 No. 2951, p. 121). — The author discusses the condition of 3 ginseng plantations 

 of considerable size which he recently visited. The ginseng had l»een planted 

 for 3 or 4 years and involved an initial outlay of considerable money. Blight 

 has seriously injured the growth and productiveness of the plantations in 

 every instance. Two of the i)lantations have been practically abandoned and 

 the third has not begun to pay expenses. 



Seed packing for the Tropics, W. II. Patterson {Gard. Citron., 3. ser., J/O 

 {1906), No. 1033, p. 255). — (termination tests were made of seed sent from 

 England to the West Indies in ordinary paper packets. The tests were made 

 (1) on receipt of the seed, (2) at the end of the month, (3) at the end of 2 

 months. The seeds germinated well at the end of the first and second months 

 and fairly well at the end of the third month in the case of beans and peas. 

 It is not deemed advisable to attempt to grow seeds that have been kept for a 

 longer period than this in the Tropics. 



Data are also given for a similar test with a large numlier of vegetable seeds 

 sent out from Kew. As a result, the writer thinks it is not so much a ques- 

 tion of the temperature and moisture as of ravages of small ants and weevils 

 after the arrival of the seed in the Tropics. 



Fruit industry {Daily Consular and Trade Rpts. [V. 8.], 1906, No. 2616, pp. 

 1-6). — Statistics are given showing the total exports of fruits from the United 

 States to different European countries in 1905. The largest amount of green 

 and canned fruit is shipped to Great Britain, while Germany is our greatest 

 purchaser of dried fruits, many of which are used for the manufacture of jelly, 

 marmalade, etc. The total exports of fruit for the year ended June 30, 1906, 

 were valued at .*? 14,964, 158. In 1904 the value was $20,347,699, and in 1905 

 $15,2P7,391. 



Statistics and fruit-crop report, A. W. Peart {Proc. Conference Fruit 

 Groicers Canada, 2 {1906), pp. 19-26). — Tables of statistics are given showing 

 the number of bearing and non-bearing fruit trees in Canada and each of the 

 provinces in 1901, the yields of the same in bushels and an estimate of the 

 value. Data on the yields, value, and acreage of grapes and small fruits are 

 also given, and tables showing the apples exported from Canada during each 

 of the 10 years jirevious to .Tune 30, 1904, and the countries to which they were 

 shipped. 



Varieties of fruit for the home orchard, H. L. Price {Virginia 8ta. Bui. 

 161, pp. 123-1 Jf.'f, figs. 13). — Brief descriptions are given of a few of the bet- 

 ter varieties of each of the different orchard and small fruits which may be
