things" left, till every graft had died. People would 

 not buy a grafted plant at any price, and hence the 

 stock went into oblivion. It seems very strange to 

 those not acquainted with the slow progress of the 

 experience of "foreigners" through the British 

 Islands to have the rose growers of that region 

 paying for their experience as freely as if it was all 

 v.fholly new. The Gardett now tells us : 



" It is, in fact, a great mistake for amateurs to 

 grow roses on the Manetti stock, for the following 

 reason : One day a gentleman asked me for advice 

 about his roses. He said three years ago he 

 bought six dozen rose bushes ; they flowered well 

 the first year, but he got very few flowers after- 

 wards. I went with him to see them, and from 

 what I saw in his garden I thought he was a clever 

 man. It was a beautiful place, and he appeared 

 to be quite a judge of a good many things ; but 

 when we came to the roses I discovered they were 

 not rose trees at all, they were Manetti stocks ; 

 indeed, there were only one or two pieces of rose to 

 be seen." 



White Pvrus Japonica. — The white Pyrus 

 japonica of American gardens has a tinge of pink 

 in it. By the following from the Gardeft, 2l. pure 

 white has appeared in England : 



"A new white variety of Cedonia japonica now 

 in full bloom in Messrs. Veitch's nursery at 

 Coombe Wood, under the name of nivalis, is 

 among the most chastely beautiful of early flower- 

 ing shrubs. The flowers are identical with those 

 of the ordinary kind, but are as white as driven 

 snow, and it retains its purity throughout the 

 flowering season, thereby differing in an important 

 degree from the common white variety of Cydonia 

 alba, which changes to a pinkish color by age. 

 This variety nivalis is, like the original, a very 

 free bloomer, and long shoots are perfect wreaths 

 of white, so abundant are the blossoms. Beauti- 

 ful as these snow-white flowers are on the bush, 

 they seem to reveal additional beauty when cut 

 and associated with a little greenery, and they last 

 a considerable time in water and half-opened buds 

 fully expand, though not such a pure white as 

 those that expand in the open air. As a com- 

 panion plant to the high colored varieties of the 

 favorite Japanese Quince the plant under notice is 

 recommended. For wreath and other floral de- 

 vices it is invaluable at this season." 



LlLiUM Harris:. — This is a variety of Japan 

 species, Lilium longiflorum, but has become natu- 

 ralized in the island of Bermuda. Importations 

 have been made from there and sold under the 

 name of Bermuda lily. 



FoRSYTHiA susPENSA. — This is the F. Fortuni 

 of English catalogues, as the leaves are both 

 simple and trifoliate on the same plant. It is a 

 far more graceful plant than the old Golden Bell, 

 Forsythia viridissima, and flowers earlier. It 



blooms, indeed, under a very low temperature, 

 and under warm shelter will be quite as early as 

 the Japan jasmine, Jasminum nudiflorum. It can 

 be trained on trellises against walls like the jas- 

 mine. It also may be led up on one stem to make 

 heads, when it is far more interesting than the 

 Kilmarnock willow. 



Paris Green on Large Trees At a recent 



meeting of the Massachusetts Horticultural Society, 

 Mr. J. W. Manning, after speaking of the univer- 

 sal prevalence of destructive insects, one following 

 another through the season, said that the most 

 effectual remedy for the canker worm is London 

 purple or Paris green, the first being preferable. 

 Being lighter it will remain suspended in the water 

 better, and its color is such that it can be seen 

 better. A slightly heaping teaspoonful to three 

 gallons of water, or a pound to two hundred 

 gallons, is about the right proportion ; but the 

 strength varies, and the exact quantity must be 

 found by experiment. If too strong it will kill 

 the leaves, and if not strong enough it will not 

 kill the worms. It should be applied in a fine 

 spray, either with a common garden syringe or by 

 a portable pump with hose attachment. The latter 

 may be placed in a wagon, with the poisoned 

 water, for convenience in moving. All the foliage 

 should be sprinkled. Sometimes it is necessary to 

 make two applicadons, but frequently a single 

 application will clear the trees for years. In the 

 grounds of Amos Hill of Belmont, where it was 

 used in 1878, and those of the essayist, who in 

 1880 applied it to thousands of apple and elm trees 

 in his nursery, few insects have been seen since, 

 and a second application destroyed these. The 

 best time is as soon as a perforation of the leaf 

 can be seen, but it has proved effectual when the 

 worms were nearly grown. 



SCRAPS AND QUERIES. 



Laurel Oak. — A St. Louis correspondent says : 

 " I do not think there is under culture the true 

 laurel leaved oak, L. imbricaria I suppose. This 

 oak grows quite abundantly here in certain soils, 

 or rather situations, and with its glossy entire 

 leaves and symmetrical growth is, I think, by no 

 means destitute of beauty. I have a lot of seed- 

 lings, both one and two years, of Yucca flaccida, 

 which I regard as a very valuable yucca, in that 

 it blooms much younger and much more freely 

 than Y. filamentosa, as I have noticed that the 

 latter requires several years after division and
