QUESTION DRAAVEl!. 



An esteemed member from Barrie, Out., writes : — 

 When my lawn was laid down last fall it was by u)istake sown with 

 orchard grass, and as such grass will never produce a velvety sward, I wish 

 to kill it. Will a deep ploughing of it this fall, leaving it rough till spring, 

 be suilicienti or if you consider this will not be enough, please be so good 

 as to tell mo the best way to manage. 



It will be more likely to kill it if plowed deep and harrowed so iis 

 completely to bury it, and not allow any of it to get 14 chance to start 

 We have found tliat grass sod is more sure to rot and die if plowed 

 about the middle of August. 



I wish to plant a few pear trees in a sheltered garden with southern 

 aspect, gravelly soil, n)oderately damp subsoil, and immediately fronting a 

 sheet of water, and tolerably free from late and early frosts. I want to 

 know the names of such tender varieties of the very best kinds that might 

 be grown under such favorable circumstances so far north. 



It is impossible without some experiment made at Barrie under 



similar conditions to speak with confidence to this question. The 



following varieties are of the very best quality, sufficiently hardy to 



thrive in the County of Lincoln, namely : Tysun, Beurre Bosc, Beurre 



Hardy, Seckel, Sheldon, Beurre d'Anjou and Doyenne Boussock, and 



might all or some of them be found to do well. We suggest that our 



correspondent give them a trial, and report results through the pages 



of the Canadian Horticulturist for the information of others. His 



experiment will be worth a thousand guesses. 



Why will not common Ivy live out of doors here the year round as it 

 does in Montreal ? 



Is the Ivy intended by the term " common Ivy" the English Ivy? 

 Canadians and Americans apply that term to a native creeper, .4m- 

 pelopsis guingwfoiia,, which is quite hardy, and should thrive without 

 any trouble at Barrie. If the English Ivy is intended, we can only 

 state that we were not aware that it did live out of doors at Montreal, 

 and very nmch doubt whether it will survive there a single winter 

 above the snow line. Below the snow line at Montreal it will be safe 

 all the winter, for the reason that tlie snow remains. Possibly (our 

 correspondent will know if it be so) at Barrie tlie snow melts at times 

 during the winter, leaving the Ivy exposed for some days to severe 

 freezing; if not, then the English Ivy should be able to live below 

 the snow line at Barrie also.
