rado potato beetle in Nova Scotia; on locusts in EgjT)t in 1891; and on 

 spraying for the codling moth. The etiectiveness of spraying has been 

 illustrated by Mr. W. F. Brown, who carefully compared 100 unassorted 

 apples taken from sprayed, and an eijual numl)er from unsprayed trees. 

 From the sprayed tree SI perfect api)les were taken, 1) that were par- 

 tially injured and 7 that were worthless, while the unsprayed tree 

 yielded only 4 perfect apples, 58 injured, and 38 woi'tldess ones. The 

 titles of other notes presented areas follows: A remarkable buttertly 

 eifCmy {Hemisaga hastata); the An goumois grain moth; mosquito larvjB 

 as supposed internal parasites; Lepidoptera. whose, females are wing- 

 less; tobacco insects in Florida; insect <liseases of the jMediterraneau 

 orange; a new locality for Icerya imrchasi, i. e. St. llelemi; the use of 

 vaseline and carbon bisulphide; a leaf miner in wheat {Lachifita prcvma- 

 tHtrUa)', and an account of the benelicial insects recently sent by Mr. 

 Koebele from Australia.

DIVISION OF STATISTICS. 



Eeport No. 94 (new series), April, 1892 (pp. 97-147). — This 

 includes articles on the condition of winter grain, horses, cattle, 

 sheep, and swine; speculation vs. industry; cotton acreage; European 

 crop report for April; and rates of transportation companies. The 

 condition of the grain croj) is reported as low, the result of unfavorable 

 conditions at time of planting and poor autumn growth rather than 

 damage by winterkilling. 



The live stock returns indicate remarkable immunity from serious 

 disease among all classes of farm aninmls. The winter was generally 

 favorable, feed abundant, and as a result, comi)arative condition is 

 quite high. Losses from both disease and exposure have been light.
