A GUIDE TO THE LITERATURE OF POMOLOGY. 427 



A recent work of Carl Mathieu, entitled " Nomenclator Pomo- 

 logicus, Verzeichnis der im Handel und in Kultur befindlichen Obst- 

 arten, mit ihren Synonymen oder Doppelnamen " (Berlin, 1889), 

 gives, as the title indicates, a list of names and synonyms with refer- 

 ences to literature, and serves therefore as an index to pomological 

 literature. It is of the greatest value in hunting up varieties, or as 

 a record of names already applied, and is the most complete work of 

 its sort yet attempted. 



There are a few periodical publications which cannot be over 

 looked, and the most important of these are the " Pomologische Monats- 

 hefte." This valuable work was first published in 1855, under the 

 editorship of Oberdieck and Eduard Lucas, as the " Monatsschrift 

 fiir Pomologie und praktischen Obstbau." It is continued at the 

 present day as the " Deutsche Obstbauzeitung," and is the organ of 

 the Deutsche Pomologen Verein at Eisenach. This is an extremely 

 valuable publication, and represents a complete history of German 

 pomology for 57 years. The coloured plates are of moderate ex- 

 cellence, and the articles are written by the best experts of the time. 

 It is at present, as far as I know, the only real pomological journal 

 published where new varieties are described and figured. 



An older work of value is " Der Deutsche Obstgartner "of J. V. 

 SiCKLER. This consists of 22 octavo volumes, and was first published 

 in 1794. The illustrations are rather crude, but valuable for their 

 date, and some interesting historical articles by Sickler himself 

 give the work a special value. The portraits of contemporary 

 pomologists are another interesting feature. 



Another publication worthy of mention is the " Zeitschrift fiir 

 Obst- und Gartenbau," published by the Pomological Society of Saxony 

 at Dresden, 1875-1908. This was called for the first three years the 

 " Sachsische Obstbauzeitung." 



The most important Pomology now being published is the 

 " Deutschlands Obstsorten " edited by MtJLLER, Grau, and Bissmann 

 This was begun in 1905, and three fascicles are published each 

 year (except in 1912 and 1913, when six parts were issued 

 in each year). Each part describes four varieties of fruits, with a 

 special full-sized coloured plate. A very important and new feature 

 is a photograph of each variety in the winter state, showing very 

 clearly the different types of growth. The fruit only is described 

 in detail, but full particulars are given as to the habit and preferences 

 of the tree, and a useful summary of bad characters. This work, 

 when complete, will form a most valuable addition, and worthily ends 

 this review of German literature. 



French Works. 



The nineteenth century in France was remarkable for an output 

 of works on fruits of a variety and excellence which have never been 

 surpassed. The works of Duhamel have been mentioned above and 

 need not be referred to further. There were, however, many other
