gardens with vigorous trees. And lience, however mistaken he was as 

 to the duration of varieties, his labours were in the direction of the pubHc 

 good, and were most successful. Although previous to his time the 

 uses of hybridisation were understood, Knight was one of the first to 

 apply it in raising improved sorts of fruit trees. In Dr. Bull's sketch 

 very full particulars are given of the work he did, and the success he 

 achieved. It may to some seem a small matter now that he gave us 

 better kinds of apples, chei-ries, nectarines, pears, plums, and straw- 

 berries, and some improved peas and other vegetables, for we are familiar 

 with improved fruits and vegetables as things of constant introduction 

 now-a-days, and we are apt to hold cheaply whatever comes easily. 

 But it is a fact to be remembered that our present plentiful supply is due 

 to the initial labours of Thomas Andrew Knight, and the example 

 he set. Dr. Bull has then done a fitting thing in giving some details of 

 the life history and work of one of Herefordshire's chief worthies in the 

 " Herefoi'dshire Pomona." 



The plan of the book in reference to the fruits described is to tell 

 the origin or history, and give a technical description of each fruit and 

 its uses, with particulars as to the soils and situations in which it has 

 been found to thrive. Each fruit is also depicted m a coloured drawing, 

 and these illustrations must have been produced at great cost. They 

 are some of the most successful instances of colour-printing we have 

 seen. It is needless to add that while greatly adorning the work they 

 add immensely to its practical value. 



" The Herefordshire Pomona" is a work to be proud of, and eveiyone 

 interested in the cultivation of apples and pears will feel bound to 

 possess himself of a copy. The second part will be issued next year. 

 Dr. Hogg, a well-known authority on Pomology, and an honorary member 

 of the Woolhope Club, has kindly undertaken the arduous labour of 

 editing the work. E. W. B.

 Whilst comparatively few of us can adequately appreciate and 

 thoroughly understand the minute descriptions of specific differences, 

 and the elaborate articles on foreign Geology which form the more 

 important records contained in the leading journals devoted to this 

 science, it is with much pleasure that we take up a work devoted to the 

 Geology and Botany of a district so near, and in many points so similar 

 to our own as West Yorkshire. Nothing tends so much to show the 

 value of local scientific societies as the publi3ation of the results of the 

 work of their niembers, especially when devoted, as is the goodly volume 

 before us, to the elucidation of the physical phenomena peculiar to the 

 several districts over which such societies claim special rights of 

 investigation. 



West Yorkshire is by no means a small area, for it contains 2,760 

 square miles ; and it will therefore be setn that the examination of the 

 Geology and Botany of so large a district is a very arduous undertaking.
