ONE JUDCiE SYSTEM. 



513. Si'r, — lu question bubget (No. 9) some oae asks, " Is the one-jiulge system at 

 fairs ail advantage over liaving three judges?" 1 do not think it is. Of course, there is 

 an advantage in having only one judge to pay instead of three, but, as an exhibitor, I am 

 a sufferer. At our fair I exhibited a peck of potato onions, as Iteautiful a sample as was 

 ever seen. We had only one judge, and he did not givo me a prize. He declared they 

 were not potato onions. Had there been three judges, no doubt I would have ha<l my 

 right. Such ignorance does societies great harm. 



Thos. Ham-Oway, Clinton, Onl. 



It i.s quite possible for three judges to make mistakes as well as one. The 

 great point is to secure competent men, and surely such can only be secured by 

 liberal reward. Were the money paid to three judges given to one, an expert 

 could be secured, in whose judgment the public would have cotifidence. This 

 would surely be better than three judges, none of whom were experts. If the 

 one judge is not an expert, it would be far better to have three. 



BLACKBERRY LEAF BLIGHT. 



514. SfR, — Many of my Kittatinny blackberry leaves are turning yellowish as f 

 with rust. I enclose samples, can you tell me what to do with them ?

Reply by Prof. James Fletcher, Central Experimental Farm. 



I have submitted the leaves to Prof. Halstead and he has decided that the 

 leaves are attacked by the fungus disease Septoria rubi, West, which is of the 

 common leaf spots of the Rubus family. It resembles very much the Strawberry 

 Leaf Blight, Sphcxrella fragaria?, which is figured in a paper on " Some Pro- 

 blems in Horticulture " read by our editor before the Hamilton Association. 

 This disease will probably yield without difficulty to the treatment of the Bord- 

 eaux mixture. Your correspondent is correct in stating that the disease is 

 injurious to the blackberry plants. 



LOCATION FOR GROWING FRUIT. 



515. Sir, — Do you think the sand in Telhani, or the soil about (irinisby best for 

 grapes and small fruits ? Wliat ought fifteen acres of good soil and orchard, or small fruit, 

 without any waste, to be worth, first, clear and under cultivation, and second, with fruit ? 

 I am offered fifteen acres or* sandy soil, cleared, for $1,3(>0. It has no buildings.

Questions like these can only be answered approximately, there is so much 

 to consider which cannot be put on paper. In some sections of country land 

 is worth more without an apple orchard than with it, because gt)od markets 

 are so inaccessible that tiiere is no ()pi)i)rtunity of si'lling tlie surplus. Generally
