GEXKIJAI, WORK OF THE DIAISIOX. 



Ever since the organization of the Division of Entomology and Botany, an object 

 of special effort has been to convey in the simplest and plainest language to farmers 

 and others for whose benefit all of the investigations are carried on, such results of 

 our work as are considered valuable and worthy of publication. In order that these 

 results and any suggestions made might be practical, no opportunity has been lost of 

 testing personally any remedy or implement recommended for use, and a special feature 

 from which such success as has been attained is largely due, has been the enlisting of 

 the empathies and securing the co-operation of practical farmers and horticulturists 

 all over the country. It is manifest that none are so likely to take notice of the results 

 of any treatment suggested as those who are actually concerned in a monetary way, 

 in the success or failure of experiments. Many original investigations into the life- 

 histories of injurious insects have been carried on every year since the work began, 

 and much of value has undoubtedly been learnt; but what is perhaps of more value is 

 that concise accoxnits of the various insect pests and of the best treatment for noxious 

 weeds and fungous diseases have been published, at the time of their injurious occur- 

 rence, of such pests as have made themselves noticeable by their sudden appearance ii. 

 injurious numbers. This has been either through the annual reports of the Experi- 

 mental Farms, or of the Agricultural Committee of the House of Commons, in bul- 

 letins, or through the daily and agricultural press.
