THE PEAR AND CHERRY SLUG. 103 



disease and red rust. I would therefore recommend the 

 same strength to be used as a spray, say one ounce to six 

 gallons of water. In case this strength is found to have 

 no effect on fusicladium^ it might he doubled, I should 

 think, without risk to tree, foliage, or fruit." 



In reading these remarks in the report on the fusi- 

 cladiums published by Mr. Crawford, of Adelaide, it 

 has occurred to me that the iron sulphate ought to 

 have a fair trial here as an insect destroyer also. It 

 has of course been tried on the phylloxera, but I believe 

 it has so fiir proved unsuccessful; let us hope for better 

 results. Mr. Byron Moore, so well known in our city, 

 from whom I have just received a letter informing me 

 that, by a liberal use of the iron sulphate, he has been able 

 to keep his tomatoes and other vegetables quite clear of 

 both insects and fungi. 



Mr. Crawford has made an estimate of the cost of 

 the above solution, being, as he says, but a mere fraction 

 of a penny per gallon. 



Luckily for the growers of pears and cherries this 

 slug is easily destroyed, so nothing else remains for us to 

 do but to attack it persistently until we have it within 

 reasonable bounds, w^hen, by a little united action, it cao 

 without a doubt, be stamped out altogether.
