of our journal, there is some comi)laint against the Blenlieim Orange on account 

 of its being shy in bearing. 



Slitting the bark will be of little use in curing cracked bark referred to. 

 Usually, the damage is already done before the injured place is observed. If 

 any reader has any experience in successfully treating this trouble, we would be 

 pleased to have the information for publication. 



LIVER OF SULPHUR. 



Sir,— Where can liver of sulphur (sulphide of potassium) be purchased at 20c. per 

 pound? I see the Country Gentleman puts it at 15c. I have to pay 40c. a pound for it, 

 besides express charges from Toronto. If it could be purchased at 20c. it could be used 

 to pay. 



Stanley Spillett, Nantye. 



Mr. Fred H. Yapp, druggist, Hamilton, says the ordinary price there is 25c. 

 a pound, but if taken in quantities of 25 and 50 pounds, 20 cents a pound. Sul- 

 phuret of potassium should be asked for, not liver of sulphur, which might be 

 understood to mean sulphur vivum. 



BOOK ON COLD GRAPERIES. 



Sir,— Is there any book published on cold graperies and the growing of vines in them ? 

 If so, please answer through the journal. I ripened some figs in my new one last year, but 

 my grape vines did not make much growth. The journal seems to be constantly improving. 



A. J. Collins, Listoicel, Out. 



So little is done in America, comparatively speaking, in cold graperies that 

 there is very little published with regard to their management. The only book we 

 know of is " Woodward's Graperies and Horticultural Buildings," which is sold 

 at $1, and may be ordered through this office. 



PLANTING GRAPE VINES. 



Sir,— I think your advice, page 89 of the February number, in reference to planting 

 grape vines, open to criticism. We have 15 acres, 8 feet in the row ; 25 acres, 6 feet, and 

 5 acres, 4 feet ; the rows in all cases are 8 feet apart. The advantages are decidedly with 

 close planting. The trellises are covered with bearing wood at least a year sooner, and the 

 problem of pruning so as to have an even distribution of good wood, is reduced to a mini- 

 mum. The only objection is the first cost of vines and planting, which is more than ottset 

 by the extra first year's crop. A. McNeill, Win<l.-:or. 



Four feet apart might answer while a vineyard is young, like, probably, that 

 of our correspondent, but how will it do when 25 or 30 years planted? We 

 hall be glad of the experience of vineyardists from all quarters on this subject.
