containing nitrogen and phosplioric acid are advised, and it is fui'tlier recom- 

 mended that in many cases mulcliing be supplemented witli moderate applica- 

 tions of nitrogen and pliosplioric acid. 



Small fruits in 1906, J. P. Pillsbury {Pennsylvania Stu. Rpt. 1907, pp. 162- 

 170). — Tabular data witli brief notes are given relative to the flowering and 

 fruiting of a large number of varieties of straw^berries, raspberries, black- 

 berries, dewberries, currants, and gooseberries being tested at the station. 

 Unpromising novelties and inferior varieties have been discarded from the test. 

 The susceptibility of the different varieties to disease is also indicated. 



Cranberry substations, W. P. Brooks (Massachusetts Sta. Rpt. 1907, pp. 

 17, IS). — As a result of the season's work the knowledge relative to cranber^' 

 insects has been greatly extended and the tentative conclusions reached as a 

 result of the first year's work (E. S. R., IS, p. 954) have been in many cases 

 confirmed. 



The fertilizer experiments being conducted at Falmouth show thus far that 

 nitrate of soda greatly stimulates the growth of vines and increases the size 

 of the berries. Acid phosphate appears to favor early maturity of the fruit, 

 accompanied apparently by decrease in size. Potash exercised the most favor- 

 able influence on the yield of fruit and appears favorable to the development 

 of a bright color. The plats to which muriate of potash and acid phosphate 

 were applied produced exceptionally solid, heavy, and fine appearing fruit. 

 Lime appears to have been unfavorable to fruitfulness. 



Through the vineyards of the Spanish Peninsula. M. Poirier (Ann. Inst. 

 Nat. Agron., 2. sen, 7 (1908), No. 1, pp. 135-183, figs. 6).—X general account 

 and discussion of viticultui'al conditions in the grape growing proA'inces of 

 Spain. 



Seasonal influence in carnation crossing relative to seed production, 

 W. Stuart {Vermont Sta. Rpt. 1007, pp. 355-3.58). — Tabular results are given 

 and discussed relative to limited studies made during the past 4 seasons. 

 The results, which are in accord with those secured by Rudd (E. S. R., 16, 

 p. 978), lead to the conclusion that crosses made early in the indoor season, as 

 in November and December, give a considerably higher percentage of successes, 

 a much larger number of seeds per capsule, and a higher percentage of ger- 

 mination than crosses made late in the season as in February. The author is 

 of the opinion that the better results secured by early crosses are due princi- 

 pally to the greater vigor of the plants. The weather conditions also appear 

 to be moi'e favorable early in the season.

Georgia's forest resources, R. M. Harper (South. Woodlands, 1 (1907), Nos. 

 3, pp. 1,-23; !,, pp. 1-19; 5, pp. 3-19; G, pp. 15-32, pis. .',. maps 13).— A system- 

 atic catalogue of Georgia trees, showing the distribution and uses of each 

 species as far as known. There are enumerated 134 species known to occur in 

 Georgia and the probable occurrence of about 20 more is suggested. Introduc- 

 tory statements deal with the factors determining the distribution of forest 

 types in Georgia and the natural subdivisions of the State, with the character 

 of the forests of each. The text is accompanied with a series of maps showing 

 the range of the more important species. The work is based upon previous 

 botanical investigations in the State, together with extensive field investigations 

 made by the author. 



Report on an examination of certain swamp lands belonging to the State, 

 W. W. Ashe (N. C. Oeol. Survey, Bien. Rpt. 1905-6, pp. JfO-50) .—This report 

 embraces the results of an examination of the most promising portions of
