EDITORIAL NOTES. 



Origin of the Manetti Eose. — Referring to 

 the origin of the Manetti Rose, a recent issue o 

 the Journal des Roses states, that it was raised 

 from seeds obtained from Persia by M. Manetti 

 at the Botanic Garden of Monza, Italy. In 1837 

 some plants were sent to Mr. T. Rivers at Saw- 

 bridgeworth, by M. Crivelli of Como, Italy ; and 

 it was introduced from England to France the 

 20th of March, 1840, by M. Portemar fils. 



Double Dahlias. — Double Dahlias are not 

 double in the sense that a double Rose, or other 

 flowers are double. The florets of the disk have 

 simply been enlarged, so as to be somewhat strap- 

 shaped as the ray florets are, instead of tubular 

 as they are normally. But it is said there is 

 now a real double dahlia — that the central 

 florets have each another or others inside of 

 them. 



Improved Wall-flowers.— One by one florists 

 are taking up the old fashioned flowers and are 

 improving them. Now it is the old Wall-flower. 

 As seen this year the new forms are very beau- 

 tiful. 



A Large Violet.— Says the Journal of Horticul- 

 ture: "We send you one bloom of the Swanley 

 White Violet, this must be the best of all whites." 

 So writes Mr. Cannell, and the flower we received 

 is certainly the finest of its kind we have seen. 

 It was exactly oneand a-half inch in diameter, 

 and contained forty petals, imbricated, and con- 

 stituting a neat and well-formed flower." 



Clover ik Lawns. — White clover is still often 

 flown with lawn grass, but few who know what is 

 what in lawn management do so any more in 

 our climate. It creeps along and crowds out 

 everything else, only to be itself burned out by 

 the first hot sun. Then we have bare places 

 which the abominable " Fall " or " Crab grass " 

 delights to occupy. The heat just suits that 

 grass. Indeed if it would start early, and not 

 leave the ground bare till midsummer, it would 

 not be such an objectionable thing. 



Pyrus salicifolia. — A note on this deciduous 

 tree may not be out of place now that the plant- 

 ing season has arrived. It is surprising it is not 

 more planted, and would be perhaps if it was 

 more generally known. It grows into a shapely 

 tree when sufficient room is allowed it to develop 

 naturally. This Pyrus attains a large size, and 



would be suitable for planting in any position 

 singly. When in flower during the month of 

 May a good tree is very beautiful, being covered 

 with its snow white flowers. It appears to thrive 

 well in smoky positions, and cannot be very 

 particular about soil, as it grows here freely in 

 poor soil. When in flower this season the bloom 

 was severely injured by frost, but in spite of this 

 it is bearing a good crop of fruit. The tree fruits 

 annually without fail. The fruits, however, are 

 of no service or beauty, but as a flowering tree 

 it is worthy of a place, and is quite distinct in 

 the foliage from other trees. The great freedom 

 with which it fruits annually has impressed upon 

 my mind that it would in all probability prove a 

 good stock for some Pears. I shall be glad to 

 know if it has been tried, and if so with what 

 results. — Journal of Horticulture. 



Health and Shade Trees.— Rufus W. Gris- 

 wold, M. D., of Rocky Hill, Conn., has some 

 remarks on the destruction of shade trees as 

 a sanitary measure, in a popular medical 

 magazine from which' we take the following: 

 " A very intelligent physician, driving up to 

 my door once on a time, said : ' You have got 

 too many shade trees; I don't like them; they 

 are unhealthy; don't you have ague?' 'Yes, 

 badly.' ' I should expect it ; you ought to have 

 these trees cut down.' ' Ah ! do you see that 

 house yonder, completely shut in by trees?' 

 'Yes.' 'They don't have ague there at all! do 

 you see that house on the corner? And the one 

 over there? And the one next? And the two 

 still further below?' 'Yes.' 'You see there is 

 not a tree near one of those dwellings ; into them 

 all the sun pours and bores all day ; there is not 

 the least interruption to it.' ' Yes, I see that.' 

 'Well, in every one of those houses they have 

 ague and fever worse than I do in mine.' *I 

 should not have thought it.' 'Not on your 

 theory. But your theory isn't good for any- 

 thing ; it doesn't hold ; you may sometimes think 

 it proven ; but if you will go to the bottom of it 

 you will discover that it isn't worth a rush. Given 

 facts upon which you build up your deductions 

 to-day, are contradicted by another equally good 

 set of facts that present themselves to-morrow; 

 and your conclusion as to the causes of ague 

 vanish. It is just as reasonable to say that my 

 neighbor has intermittent in his family because 

 he has n't any shade, as to say that I have it in 

 mine because of the shade. As the actual fact, 

 neither the trees nor the lack of them has the
