circulation. In these articles will be found a full account of the life history and devel- 

 opment of the insect, characters by which it may be recognized, and what were at that 

 time thought to be the best means of fightin'j; against it. Ever since it became known 

 certainly that this scourge had effecled a footing in our orchards, great anxiety has been 

 shown by fruit growers in all parts of the Dominion, to obtain reliable information 

 about it. Numerous specimens of various kinds of insects, fungi, corky excretions on 

 the bark, etc., have been sent in for examination. The importance of every one concerned 

 being enabled to recognize this pest as soon as possible, so that prompt action might be 

 taken to control it, suggested the advisability of issuing last summer a large wall poster 

 which could be put up in conspicuous places such as post offices, railway stations, news- 

 paper offices and public halls throughout the district, where the scale was likely to occur. 

 This poster (2 ft. 3 in. by 1 ft. 8 in.) was got up much in the same form as a 

 similar poster issued by Prof. Webster, the State Entomologist of Ohio, on the same 

 subject and gave the excellent illustrations prepared by direction of Dr. Howard, the 

 United States Entomologist, showing an infested pear and a piece of a branch, also 

 enlarged figures of the female insect and her scale. The object of this poster was to warn 

 fruit growers that the scale was already in Canada and that if it were allowed to spread 

 great loss would certainly result. The best way to recognize the pest was given, with 

 advice as to the course to pursue, should it be discovered in an orchard.

A great deal has been written concerning the San Jose Scale since its unfortunate 

 introduction into the East, and its detection as a serious enemy of fruits by Dr. Howard 

 in August, 1893. This scale has been treated of at considerable length in previous 

 reports of this division, and numerous articles in government publications are accessible 

 to any one who wishes to inform himself on the subject. 



For the purposes of this report, it seems more useful to give a concise account of 

 the insect, its appearance, so that it may be recognized, its life history, occurrence in
