greenhouse, and will do well : and they will bloom on the north aspect of 

 your stables ; they bloom well on such an asi)ect in Scotland, Possibly the 

 Mandevillea will do on a wall in your climate. It is worth a trial. 



G. W. S. Clericus. — The hour at which your vinery fire is made up for the 

 night is quite correct. As to whether it should be made up again to any ex- 

 tent in the morning depends entirely on the state of the weather. To have hot 

 pipes when the temperature can be kept up without such, is most undesirable. 

 Generally speaking, you cannot depend on a fire made up at 4 or 6 p.m. lasting 

 with sufiicient power till 6 a.m. The true method of diminishing the amount 

 of fire-heat is to shut up your vinery early with sun-heat, starting the fires in 

 time to prevent the temperature from falling below the minimum at 10 or 11 

 P.M. A little air left on all night is beneficial, especially as the season be- 

 comes more warm. 



J. C. — An Acacia of some sort, but we cannot name it from the morsel sent. 



J. P, —The person to whom you refer is, we believe, perfectly trustworthy in 

 reference to your want. 



D. M'C. — Unheated glass walls may suit your purpose. But we recommend 

 all such structures to have means of protecting against late spring frosts in such 

 a locality as yours, for the crops are sometimes destroyed in unheated ones. 



Cam. — "We cannot undertake to name Mosses. There is an illustrated work 

 on Cryptogams by Mr R. Stark. 



Winifred. — We certainly should not think of setting up a model of a flower, 

 garden for a floral device, although the terms device and design are of the 

 widest application, and may refer to either a flower-garden design, or that of 

 an edifice. Surely schedule-framers can have no difficulty in wording them so 

 as to prevent such confusion of ideas. 



Clematis Jackmanii perfectly Hardy in the Noe-th. — In reply to your 

 correspondent Miss Hope, I may say that while travelling in the vicinity of 

 Castle Menzies, about three miles north of Aberfeldy, in Perthshire, in August 

 of 1870, I was struck by seeing C. Jackmanii completely covering (what appeared 

 from the public road to be) a wire arch in the middle of an open garden 

 without any protection from any side, and the profusion of its blooms was be- 

 yond anything I have ever seen. I would not have been half so much surprised 

 to have seen it at Wardie Lodge. D. Irvine.

The Destruction of Ants. — In the last month's issue of the 'Gardener' a 

 correspondent wished to know the most effectual means of destroying ants. 

 Though I will not say that what I am going to recommend is the most effectual 

 means, I will say that it is certain death to all of them it comes in con- 

 tact with. Those who have not been pestered with this most inveterate de- 

 linquent have great reason to be thankful ; for among all the living pests that a 

 gardener has to contend with, this, I think, is the most troublesome of them aU. 



This is my plan. My hot-water pipes are much the same as a correspondent 

 describes his. Near their principal haunts I lay down a little half-putrefied 

 raw meat minced small daily. The ants soon gather to the feast in myriads ;
