was even greater than with either soil or manure. The infection was less in 

 each case with the late planted wheat. Smutty bran was able to infect the 

 seeilliii.si wheat when sown in the drills with the seed. 



Some observations on bean rust, (i. Gassnek {Rev. Secc. Agron. Univ. Mon- 

 tevideo, 1908, No. 4, pp. 125-129, fig. 1 ) .—The attacks of this fungus ( Uromyces 

 appendiculatus) were so severe in 1908 at the experiment station near Monte- 

 video that much of the crop was lost, mainly on account of the badly rusted 

 condition of the pods. Experiments undertaken with 13 varieties to discover 

 if i)ossible resistant varieties showed that several were only slightly attacked 

 and those may, therefore, i)rove of value in coml)ating the rust. 



Diseases of celery, H. Klebahn (Ztschr. Pflanzciikmnl:, 20 {1910), No. 1. 

 pp. l-Z/O, pis. 2, figs. Ui). — The author briefly discusses celery culture and gives 

 extended descriptions of some infection experiments with two of its common 

 diseases, leaf spot and scab disease of the roots and crown. The conclusion 

 is reached that the leaf spot is caused by Srpfona apil and the scab by Phoma 

 apiicola. 



The remedies recommended for the leaf spot are Bordeaux mixture, and for 

 the scab treatment of the soil with disinfectants. As the pycnidia of both 

 diseases are found on the seed, an ajipliciition of Bordeaux might be of value 

 to both the seeds and the seedling.s. 



Potato diseases in Ireland, G. H. Pethybridge {Dept. Agr. and Tech. Instr. 

 Ireland Jour.. 10 {1910), No. 2, pp. 2^1-256, j)ls. 7; ahs. in Farmers' Gaz., 69 

 {1910), No. 7, p. 130, figs. 2). — The results are given of numerous experiments 

 conducted at a temporary experiment station at Clifden in Western Ireland in 

 1909, with special reference to a further study of the various diseases of the 

 lX)tato and to determine, as far as possible, the best means for controlling them. 

 Late or black blight {Phytophthora infestans), yellowing or yellow blight, stalk 

 or Sclerotium disease {Sclerotinia sclerotiorum), black stalk-rot or black leg, 

 and Spongospora scab {Spongospora suMerranea) were studied and methods of 

 control suggested for each. Mention is also made of leaf curl {Verticiliiiim 

 aWo-atrum), black speck scab {Cortieiuni ragvin sohuii). and violet root rot 

 {Rhizoctonia riolaeea). 



Spongospora scab of potatoes, G. H. Pethybridge {Irish Nat., 18 {1909), 

 No. 5, pp. lis, 119; ahs. in Hot. Centbl, 113 {1910), No. 1, p. 19).— After tracing 

 the history as revealed in the literature of this potato fungus, the conclusion 

 is reached that the correct name is Spongospora suhtrrranea. 



Potato-spraying' at the Grafton experiment farm, A. H. Hay'wood {Agr. 

 Gaz. N. 8. Wales, 21 {1910), No. 1, pp. 63, 6-'i). — These experiments were 

 undertaken to ascertain the cost per acre of thoroughly spraying the potato 

 crop for late blight {Phytophthora infestans). The outfit including all acces- 

 sories cost about $65, and consisted of a good spray pump with 4 single spray 

 nozzles, carried on a one-horse wagon, and required the services of 2 men to 

 run it. The spray used was 6 : 4 : 40 Bordeaux mixture applied at the rate of 50 

 gal. per acre. The capacity of the outfit was acres per day and the cost of 1 

 application was estimated at 85 cts. per acre. 



Old and new enemies and diseases of berries, G. LIjstner {Amtsltl. Landw. 

 Kammer, Wieshaden, 91 {1909), Nos. 15, pp. 102, 103, fig. 1; 16, pp. 107, 108, 

 fig. 1). — This deals with the American gooseberry mildew {Sphcerotheca mors- 

 uva') and leaf spot {Glceosporium ribis) on currants and gooseberry plants. 



A description of the leaf spot disease is given, accompanied by drawings 

 showing its gross and microscopic characteristics. Bordeaux mixture is recom- 

 mended as a remedy. 



In the second paper, 8. mors-uvcp is discussed and figured. This disease 

 attacks all parts of the plants, leaves, stems, and fruits. Several varieties of
