in different mountainous districts to determine the influence of nitrate 

 of soda on grapes and the effect of early and late applications. The 

 soil was naturally well supplied with mineral matter. The nitrate was 

 applied at the rate of 300 kg, per hectare. It was especially effective 

 on the steep hillsides. Its influence was noticeable in the greater wood 

 growth, the larger size of the fruit, and the darker green of the leaves. 

 The leaves also hung on the vines about two weeks longer than where no 

 nitrate was used. Even late applications of nitrate of soda produced 

 no harmful eft'ects. The good effect of the nitrate was not so notice- 

 able in rich, humus, clay soils in the valleys. The must from the fer- 

 tilized and unfertilized plants showed no essential difference in speciflc 

 weight, sugar or acid content, and the wine was similar in chemical 

 character. There was considerable difference, however, in the nitro- 

 gen content of the wine, that from the fertilized Amines being 10 per 

 cent higher than that from the nonfertilized vines. The leaves of the 

 fertilized vines were likewise richer in nitrogen. 



In conclusion, the author states that no harmful influence whatever 

 could be detected from the use of nitrate of soda, even with late appli- 

 cations. Wherever diff'eren'-es were noticeable they were alwa3^s in 

 favor of the nitrate.

 table, flower, and fruit gardening in (irermauy is considered, some statistics on seed 

 production, fruit imports and exports, cut-flower and plant production being 

 included. 



Vegetables, A. J. McClatchie {Arizona Sta. Rpt. 1900, pp. l'>8-161). — Cultural 

 notes and the results of tests of varieties of cabbage, lettuce, watermelons, onions, 

 and cauliflower. Succession, Fottler Brunswick, Large Late Drumhead, and All 

 Sea.sons cabbage gave the heaviest yields per acre. New York and Tyrol produced 

 the largest heads of lettuce. Of the watermelons tested Augusta proved the most 

 satisfactory. In the culture experiments with onions slightly better results were 

 secured when the plants were sown in place and thinned than when they were 

 transplanted. The variety Prize Taker gave the heaviest yield and produced the 

 best quality of onions.

The cultivation of Znaim cucumbers, .J. G. Smith ( U. S. Dept. Agr., Section of 

 Seed and Plant Introdnction Circ. 2, pp. 4)- — Notes are given on the culture and cost 

 of production of cucumbers at Znaim, Austria. The Znaim cucumbers are a variety 

 of Cucumis .sr///t'!(.s,'and are extensively cultivated for export as pickles, salted, spiced, 

 preserved in sugar, or flavored with nuistard. The seed of this cucumber has been 

 obtained for distribution among the agricultural stations of the country.
