A-v International Horticultural and Floricultural Exhibition 

 is to be held in Hamburg at the commencement of September, 1869. The sub- 

 jects of exhibition are to be arranged in three principal classes : the first is to 

 embrace cultivated vegetables, fruits, and flowers ; that is to say, all kinds of 

 produce of the kitchen-garden, flower-garden, conservatories, hot-houses, and 

 greenhouses, including shrubs, conifers, and nursery-plants ; also cut and dried 

 flowers, and selected baskets of fruits. The second includes garden-buildings 

 and appliances, such as greenhouses, hot-houses, screens, water-carriers, trans- 

 planting-machines, syringes, heating-apparatus, cutting-tools, and cutting-ma- 

 chines, contrivances for fumigating ; also rustic bridges, summer-houses, rock- 

 work, fountains, &c. The third, for produce not included under the preceding 

 di\nsions, is to include cereals, seeds, fruits, and produce occupying an undeter- 

 mined place between gardening and agriculture ; embracing forest and vegeta- 

 ble produce of all kinds, and from all countries, as employed for food, medicine, 

 or other purposes. The guaranty-fund has been arranged, and a site secured 

 in the south-western suburb. It is in the form of a park, on very high ground, 

 which commands a picturesque view of the River Elbe and of its shipping, and 

 of the surrounding scenery. Dr. C. H. Merck is chairman of the committee ; 

 Senator C. De Chapeaurouge, vice-chairman ; Mr. Edward L. Behrens, treas- 

 urer ; and Dr. Donnenberg, Dr. Gotze, and Dr. H. Merck, secretaries. Com- 

 munications are to be addressed to Dr. Donnenberg and Dr. Gbtze, advocates,

The Ravages of Insects. — The following remarks by N. C. Meeker, from 

 the proceedings of the American Institute Farmers' Club, " New- York Tribune," 

 Aug. 25, 1868, deserve attention : — 



"We may say positively that destructive insects are increasing every year, 

 and that they destroy as great an amount of food as is saved. To meet these 

 scourges will require our best efforts. The science of entomology, by which in- 

 sects are classified and their nature studied, is becoming of national importance ; 

 and we are sure, that, without its help, little will be done. The first step in every 

 pursuit is analysis, by which we separate a whole into parts ; upon each of which, 

 attention is to be fixed. Here progress commences. One of the first results in 

 this study is to make distinction between insects which are useful and injurious ; 

 for, unless this be done, one will be as likely to destroy his friends as his ene- 

 mies. At present, this study is so far from being popular, that the greater part 

 of educated men, so called, are as ignorant as the unlettered. It is manifest 

 that the elements of this science should be taught in our common schools, if it 

 is to become of much use ; for the transmission of learning directly from the 

 learned few to the common people, without the intervention of a teacher, is im- 

 possible. In fitting teachers for their duties, a knowledge of this science should 

 be included among their qualifications, as much as of arithmetic or grammar. At 

 present, however, we have no colleges where studies of this practical nature are 

 pursued, except incidentally ; but, when the agricultural universities shall be 

 fairly establislisd,. we may expect tliat tke need indicated will be fairly sup- 

 plied."
