elaborate and complex, and to some rosarians rather unsatisfactory. 

 It is easy to say that we desire a simpler and more useful arrange- 

 ment which will give more complete information as to the members 

 of the Roses in the different classes. It is a more difficult thing to 

 devise a scheme that will satisfy these requirements. How far the 

 nine writers who have attempted to find a solution of the difficulty 

 have succeeded in their object is a question on which opinion is likely 

 to differ and which the future must decide. 



There can be little doubt of the increasing eagerness among Rose- 

 growers to find a method of dealing satisfactorily with fungus disease. 

 Whether this arises from the increase in the number of Roses grown 

 in this country, or from any decrease in vitahty and hardiness of 

 constitution of our modern Roses, or again from the fact that these 

 diseases occur chiefly in late summer and early autumn, and the 

 great development of autumn Roses causes us to expect to enjoy 

 our Rose gardens at a time of the year when formerly they were less 

 interesting than we now expect to find them, or from some other 

 cause, there can be little doubt that if these diseases could be banished 

 the appearance of our autumn Rose gardens would improve. The 

 subject is treated by several writers of practical experience in the 

 treatment of Roses, and it may be that success will ultimately be 

 found to lie in the domain of the preventive medicine of the Rose. 



Though these two subjects are the most elaborately treated, 

 there are several readable articles on other matters of perhaps more 

 general interest, e.g. on the lasting quahties of cut Roses, on the pro- 

 duction of new varieties, on budding Roses and other like topics. 

 The volume concludes with Mr. Mawley's well-known Rose analysis 

 for the previous year, which he has now compiled for many years 

 in succession, giving the position of the different varieties as measured 

 by their success at the different exhibitions of the Society. 



" A History of Botany, in the United Kingdom, from the Earhest 

 Times to the End of the Nineteenth Century." By T. Reynolds

This valuable work, issued after the author's lamented death, is 

 most fascinating to read, and will long remain the standard work on 

 the subject, which the author has so admirably treated. The import- 

 ant Index contributed by Miss M. Knight, M.Sc, will be found to 

 supply not only the name of every botanist of note from the sixteenth 

 to the twentieth century, but a most important " Chronological Table " 

 of their works. The whole book comprises some 650 pages. 



It contains six " Books " entitled " Early Botany and the Herbal- 

 ists " ; " The Rise of System " (Ray, Morison, and Grew) ; " Ray to 

 the Linnean System " ; " Ascendency of the Linnean System " ; The 

 Revival of the Natural System " ; " Lindley to Darwin " ; " The 

 Origin of the Modern Revival " ; " The Wave of Progress."
