An experiment in Swedish turnip culture, F. W. Card (Rhode Island Sta. 

 Rpt. 1907, pp. 265-273, pis. 10). — The results of this experiment indicated that 

 the turnip grows best on a garden soil which is sandy rather than silty or 

 claj^ey. Lime was not beneficial except on a humus soil. Commercial fertilizers 

 increased the tops more than the growth of the roots. Potash was the most 

 advantageous Ingredient and when combined with phosphoric acid gave better 

 results than any other combination of commercial fertilizers. The use of sul- 

 phate of ammonia gave but a slight increase in yield, and the use of nitrate of 

 soda and dried blood gave no beneficial results. Barnyard manure gave an 

 excellent total yield, but scab was more prevalent than where commercial fer- 

 tilizers were used. Ashes showed no increase in root growth but apparently 

 increased the growth of the tops about 50 j)er cent. A moderately dry soil gave 

 better yields than a very wet one. Lime was beneficial when applied with the 

 commercial fertilizers. 



HOETICULTURE. 



[Horticultural investigations in Alaska], C. C. (iKOROKSON, K. W. Dk 

 Abmoni), F. E. Rader, and C. W. H. Heideman (Alaska ^tas. Ritt. V.)07. pp. 21-2'), 

 •U-.'il, '/7-4.9, 50-53, 7.'/-87. figs. 3). — Notes are given on the varieties of fruits, 

 ornamentals, and vegetables being tested at the 8itka Station, fruits and vege- 

 tables at the Rampart Station, and vegetables at the Copper Center Station. 

 More than 12,000 fruit trees and shrubs, as well as a large amount of seed, were 

 sent to various parts of the Territory, and the results secured with some of 

 these lots are given in letters from several of the stations' cooperators. 



At the Sitka Station, where the work with fruit is more advanced, the Hyslop 

 and Yellow Transparent apples bloomed during the ]iast season, but bore no 

 fruit. These \arieties. together with the Whitney crab and the Peerless, give 

 considerable promise. Other varieties are doing poorly. It appears certain 

 that only the so-called sunmier varieties can mature in Alaska, since in the 

 interior the season is too short, and in the coast region the summers are too cool 

 to mature fall and winter apples. The experiments also indicate that dwarf 

 trees are likely to succeed best. 



Of the four varieties of cherries growing, the Early Richmond and English 

 Morello are the best. Currants, gooseberries, and raspberries do well in Alaska. 

 The Cuthbert raspberry has done particularly well iu the coast region. The
