Irrigation Methods. A timely up-to-date book 

 on the practical application of the new meth- 

 ods for destroying insects with hydrocyanic acid 

 gas and carbon bisulphid, the most powerful in- 

 secticides ever discovered ; by Willis G. Johnson, 

 formerly professor of entomology and invertebrate 

 zoology at the Maryland Agfricultural College and 

 State Entomologist, author of many special reports 

 on economic topics, and associate editor American 

 Agriculturist weeklies. An indispensable book for 

 farmers, fruit growers, nurserymen, gardeners, 

 florists, millers, gjrain dealers, transportation com- 

 panies, college and experiment workers, etc. 

 Nothing of the kind has ever been printed before. 

 It embodies years ot careful research and practical 

 application by the author, as well as the tests 

 and experiences of others from all parts of the 

 world. The fruit, nursery, floral and grain indus- 

 tries are confronted on every side with hordes of 

 insect pests which threaten their very foundation. 

 This important work tells just what to use and how 

 to apply it to save serious losses from insects. The 

 author has presented his subject in a popular style, 

 free from technicalities. Specific and minute dir- 



ections are given for making and applying hydro- 

 cyanic acid gas from every standpoint. The physi- 

 ological effects upon animal and plant life are fully 

 illustrated and discussed. Six chapters are de- 

 voted to orchard fumigation, including the con- 

 struction and management of allkindsof apparatus 

 devised and successfully used. In three chapters 

 on nursery fumigation, the construction, manage- 

 ment and methods of preparing young trees for 

 treatment are given. The destruction of insects in 

 gfreenhouses. mills, elevators, granaries, dwell- 

 ings, ships, cars and other enclosures can be easily 

 and cheaply accomplished by following the direc- 

 tions g^ven. Other chapters contain the opinions 

 and methods of experts from every part of the 

 world where the gas is used. The regulations of 

 foreign governments regarding the importation of 

 American plants, trees and fruits are described. A 

 most useful part is devoted to the use of carbon 

 bisulphid for the destruction of animal life below 

 the surface of the ground, stored grain or other 

 materials, and in places where hydrocyanic acid 

 gas cannot be used. Illustrated ; five by seven 

 inches ; three hundred and ninety-one pages. 

 Cloth, $1.50.

SPEAYING PAYS 



IN a year like the present when the con- 

 ditions are commonly known as 

 rather adverse, favorable opportuni- 

 ties arise of testing many of the principles 

 or orchard practice. For example, in the 

 early part of the season we have had a 

 great deal of rain, and spraying operations 

 were frequently interrupted and in many 

 cases entirely prevented. As the season 

 advanced the weather was very moist, and 

 consequently conditions for the develop- 

 ment of fungous diseases very favorable. 

 It is not to be wondered at, therefore, that 

 many reports are coming in from different 

 parts of the province saying that apple 

 scab, mildew, grape rot, etc., are very pre- 

 valent. However, under these most un- 

 favorable conditions we find cases where 

 spraying was thoroughly carried on and 

 the rot almost entirely eliminated from the 

 orchard. Frequent reports have come in 



where the entire crops of plums have been 

 lost through the plum rot. Last week, in 

 travelling through the Niagara district, we 

 visited the orchard of Mr. E. D. Smith, 

 Winona, and found that by thorough spray- 

 ing his trees were hanging with a splendid 

 crop of fruit. On a considerable portion 

 of his orchard the fruit had been thinned 

 so that it did not touch, and where this was 

 done the trees were entirely free from rot. 

 However, even on unthinned trees which 

 had been thoroughly sprayed very few rot- 

 ten plums could be found, although the 

 fruit was so thick that the plums were 

 touching one another and crowded closely 

 together. A couple of trees which were 

 left unsprayed lost their entire crop 

 through the rot. An instance of this kind 

 affords a striking illustration of the value 

 of spraying.
