month, and written on one side of the paper only. It is also requested that 

 writers forward their name and address, not for publication, unless they wish it, 

 but for the sake of that mutual conlidence which should exist between the Editor 

 and those who address him. We decline noticing anu communication which is 

 not accompanied with name and address of writer. 



Errata.— l\i the article on Passiflora Quadrangularis, page 169, line 10, instead 

 of " exerted no influence on more than a dozen other varieties," read "exerted no 

 influence on P. Quadrangularis, more than a dozen other varieties." 

 Page 152, five lines from top, read ''Ivies'' for ''Irises." 



^y. HORNCASTLE.— "The Forester," by J. Brown, LL.D., Blackwood & 

 Sons, is the best work on the subject of Forest Trees. 

 ]Sr. King. — Many thanks. We are already supplied. 



"A Young Reader" is very anxious for a chapter on the management of Ste- 

 phanotis floribunda. Will any of our correspondents oblige by giving their 

 experience of its culture ? 



A Subscriber. — Unless we could see your vines and examine the soil, we can- 

 not pretend to give a satisfactory reason for your failure. There are two ways by 

 which the side-shoots come to drop off. If they are tied down to the wires too 

 soon, or all at once instead of gradually, they stand the strain at the time, but in 

 many cases drop off" a few hours afterwards ; or they may drop ofi" by the force of 

 their own weight, if not tied in proper time. We suspect the latter of these is not 

 the cause in your case. Get some experienced gardener to look at them ; a fourth 

 part muck, as you term it, is far too great a proportion for a vine-border. 

 D. J. — Received with thanks. 



W. W. — Sow the seed at once in light rich soil in ordinary seed-pans, using a 

 compost of equal parts peat and light loam, and place in a temperature of 60°. 

 When large enough to handle freely, prick off in pans or boxes, or pot singly in 

 small pots ; harden off when well established, and grow in a cold frame through 

 the summer. If they do well, they may throw a single flower the third year. 



A. Simpson. — Canavalia gladiata is one of the Leguminosse, a native of East 

 Indies and tropical Africa, and consequently requires warm stove treatment. 



J Q., B. — You are doubtless right in your views of the remorseless way in which 

 the Lapwing is destroyed, and of its value as an insect destroyer ; but so long as 

 there exists such a demand for them by the rich there will be boys to carry on 

 the work of destruction. 



W. Hinds. — We are much obliged. 



J, D. — Your arrangement for the centre is very good. We would prefer to 

 have 9 and 11 both with the same plant ; either Wigandia or Ferdinanda. Next 

 to these centre plants it would be advisable to have a row or two of some 

 taller plant before beginning with the Pyrethrum. Two rows of Iresine would do 

 very well, or next the tall green centre plant a row of Cineraria maritima, then 

 a row of Iresine, filling up with the Pyrethrum. 8 and 10, seeing that in all other 

 respects the group is complimentary, should also be of the same plant. 6, 6, we 

 should rather have of variegated DactylisorvariegatedPolemonium,either of which 

 are much more easy and graceful-looking plants than Gnaphalium for such a bed. 

 With these alterations the group would look very well. 



Maggot in Cineraria Leaves. — Like your correspondent W. H., I have 

 grown Cineraria in large quantities from seed some years, but never saw the maggot 

 he speaks of until last year, when it bored its way through the inside of almost 

 every leaf, making a sort of irregular white-looking network. Sometimes I found 

 three or four at work on one leaf — in fact, for fear they should get on the other 

 plants, I was obliged to cut what flowers were out, and throw the plants away. 

 Notwithstanding this precaution, they attacked the leaves of the Chrysanthe- 

 mums in the same manner just before flowering, which necessitated the removal 

 of all leaves infested, much to the injury of the plants, both in appearance and 

 flowering. I have about sixty plants of Cinerarias just coming into flower this 

 year, but I have not seen anything of the maggot yet. 



If, through the medium of your very practical journal, any means of destroy- 

 ing this pest without injury to the plant can be given, it will much oblige, 

 yours respectfully, Amateur.
