jured, if possible to prevent it. Sudden bursts of 

 sun, insects, escape of gas from the flues, very low 

 or high temperature, too much or too little water, 

 any one of them will come unexpectedly, like a thief 

 ia the night, and rob you of all your anticipated 

 fruit, if you only allow them the least chance of a 

 foothold on the leaves.

DER WEINSTOCK UI^D DER WEm, 



by horticola. 

 Praktisch Wissenschaftliche Abhandlung 

 uber die zucht des wienstocks und die 

 Bereitung DER Weines. Nach eignen Erfah- 

 rungen und Untersuchauzen eingchend und tarr- 

 lich dargestadt von Friedrich Mohr, Doctor der 

 Philosophie und Medicin, Medicinalrath, etc., 

 etc. Coblentz, Hoelschcr. 

 We deem it our duty to call the attention of such 

 readers as understand the German language, to this 

 most excelleno work. Its author, who has devoted 

 his whole life to the study of the Natural Sciences, 

 ranks among the first chemists of the age. He has 

 published numerous works, all of which are acknow- 

 ledged to be classical, i e., his admirable Commen- 

 tary on the Prussian Dispensatory (Pharmacopase 

 Borussettia"), in two volumes. One of his works 

 (" Pharmaceutische Technik"), on the manipula- 

 tions and technical operations necessary to be ac- 

 quainted with in order to carry on the drug busi- 

 ness, has been translated into English. We do not 

 recollect, however, the exact wording of the title. 



The work is dedicated to the Queen of Prussia. 

 Those conversant with European customs, know that 

 the permission to dedicate a book to a Queen is 

 never granted to a common man for a common 

 book. 



Dr. Mohr, living on the EJime where the Moselle 

 unites with it, had unparalleled facihties for study- 

 ing practically, by observation, the different me- 

 thods pursued by Vignerons, of managing vines 

 and vineyards, as well as those of making wine. 

 His profound knowledge of Vegetable Physiology 

 and of Chemistry enabled him to corroborate and 

 explain scientifically some of them, and to show up 

 the absurdity of others. Bis work does not inter- 

 fere with any extant ; on the contrary, it forms the 

 foundation for them all. It does not teach new 

 methods of pruning, pinching, training, etc. ; bilt 

 it shows the basis on which those operations rest, 

 and the objects for which they are intended. 



It is absolutely impossible to make extracts from 

 a book, teeming with matter so important. We 

 will, however, mention here the physiology of the 

 vine, the development and structure of it, the 

 causes for pruning and the pruning itself, the treat- 

 ment of the vine during the summer, the manuring 

 and the quality of the manure, the bleeding of the 

 vine and the chemical analysis of the fluid lost by 

 bleeding, the grape-vine disease, etc. 



The second part (not volume) of the work, which 

 treats of wine making, is equally interesting; but 

 as many more persons plant and cultivate vines 

 than make wine, we confine ourselves here to the 

 contents of the first part. 



The author has no acknowledgments to make ex- 

 cept to Kecht; his investigations and the results of 

 his experiments are original. To gain positive, sci- 

 entific knowledge, he had more space twenty years 

 ago, — a trellis erected 800 feet long on which to 

 grow his vines. He planted, besides, about an acre 

 of ground to Grrape-vines at his farm near Coblentz. 

 Surrounded, moreover, by the most celebrated vine- 

 yards of the world, and by scientific and skilful 

 vineyardists, he was so circumstanced and so many 

 advantages were united in him as have never taken 

 place before in the whole history of Viti-culture, and 

 will hardly ever take place again. 



Dr. Mohr's admirable book ought to be in the 

 hands of every cultivator of the vine who under- 

 stands the German language. Written by a man 

 who is master both of his subject and of his lan- 

 guage it is intelligible to all. 



We are engaged in the translation of the first part 

 of this book into the English language, and shall 

 soon publish it with some additional remarks on the 

 propagation and the general management of the 

 American varieties. We are so situated that we 

 cannot perform this task without much inconve- 

 nience ; still, we think it our duty to introduce a 

 work to this country, than which there does not 

 exist a similar one in any literature. 



TILDEN TOMATO. 



BY JAMES HOLDING, HAMMONTON, N. J. 



I see a communication in the Monthly from Mr. 

 Robert Sinclair, of Baltimore, Md., noting the Til- 

 den and Cook's Favorite Tomatoes as identical, and 

 condemning them both as" vegetable humbugging." 



Mr. S. must be mistaken in them with re- 

 gard to identity — they are very distinct. I am sat- 

 isfied I have the Tilden, and I think I have the 

 Cook's Favorite. Had them, this year, growing by 

 the side of others, including Fejee, Lester's Early
