The vapor of tobacco is not onlj- very effective in destroying insects where it can be confined, as in green 

 houses, but it is less injurious to delicate plants than either the smoke or the liquid. Hence, instead of fum- 

 igating greenhouses, it is customary now to strew the ground under the plants with tobacco stems, which being 

 moistened by the syringing creates a vapor which is destructive to insect life. This method will probabl) 

 supersede the old way of fumigating ^^-ith tobacco smoke, which we have always found, up to the present time, 

 the best mode where appliances can be had for confining the smoke; this, however, is not very convenient fo"- 

 use in dwelling houses, but we have other excellent remedies which are more practicable. Take four ounce? 

 of quassia chips, and boil them ten minutes in a gallon of soft water ; strain off the chips and add four ounce, 

 of soft soap, which should be dissolved in it as it cools, stirring well before using. It may be applied with r 

 clean painter's brush of moderate or small size, brushing ever)- leaf and shoot that is infested. After fifteen 

 or twenty minutes have elapsed, the plants should be washed or syringed \\-ith pure water. Another good 

 remedy is the same as above only tobacco stems — say a quarter of a pound — are used instead of quassia. 



In the month of May, or as soon as the leaves have pushed forth, the rose caterpillar makes its appear 

 ance ; he can readily be detected, for he glues a leaf or two together to form his shelter. Every day the bushes 

 should be gone over, and these glued leaves pinched between the finger and thumb, so as to crush the cater- 

 pillar ; let no fastidious grower neglect this, or be induced to try other remedies ; this is the only one that Is 

 simple and effective. For other insects, such as the saw fly, larvae, and all such as come at a later date thai, 

 the caterpillar, an occasional syringing, vigorously applied, will prove an excellent preventive. When they 

 have made their appearance, a sprinkling of powdered white hellebore over the plants will often destroy o: 

 disperse them ; but the plants should be well moistened before the hellebore is applied, so that it will remain 

 The red spider may be generally kept off by keeping the plants daily syringed with water. When plants are 

 once infested with this dreaded insect, the fumes of sulphur will alone disperse or destroy them. This appli- 

 cation \\-ill, of course, cause the foliage to drop off, but it is the only remedy we know to be efficacious. Thf 

 red spider very seldom attacks plants in the open air, but confines itself to the plants under glass. 



For the rose bug, hand picking must be resorted to, for, like the red spider, it is proof against hellebore 

 whale-oil soap, and all such applications. 



Mildew. This disease is generally caused by extremes of heat and cold, and by a long continuance o-l 

 damp, cloudy weather. The best remedies are sulphur and soot ; one of these should be applied the moment 

 the disease makes its appearance. It is a good plan to previously sprinkle the plants with water, so that ths 

 substance applied \\-ill adhere. 



ADVICE TO CORRESPONDENTS. 



See also Page 1. 



In case budded plants are ordered, state whether we shall send the same varieties on own roots, in cas-^ 

 we cannot supply them budded. This is necessary where parties ordering have any preference for either 

 mode. lVhe7i ttothing is said we exercise our best judgment, and if out of budded plants setid those on their owr, 

 roots, and '-vice versa.'" 



Amateurs in ordering will do well to leave the selections to us so far as possible, btit our list is open to 

 all to make their own selections. Purchasers, however, will please say if they wish us to substitute in case all 

 the varieties ordered cannot be supplied. In such case we always endeavor to send something better where 

 it is possible, than the kind called for. We do not substitute luitho'ut beifig requested to do so. 



Roses by Express. When no directions are given as to what way the plaiits are to be sent, we always for- 

 -ward by Express at the purchaser's cost. The plants which we send in this way (except the new and ven" 

 scarce varieties) are one-year-old buds, or one to two-year-old plants on own roots, and are dormant. Thes:- 

 plants are the only ones stiitable for immediate effective results. 



Note carefully the habit of growth as stated in the description, and you will not be disappointed in thr 

 size of the plants. We have the very best quality of each kind that it is possible to grow. 



ARRANGEMENT. 



We divide the Rose Department of the Catalogue into two divisions : 



Division i. Summer Roses, or those which bloom in June and July only. This includes the A\Tshire, 

 Prairie, Austrian, Damask, Provence, Hybrid China or Gallica, and Moss classes. 



Division 2. Perpetual or Autumnal Roses, or those which bloom more than once in one season: 

 many of them bloom at intervals from May to November, notably the Teas. Hvbrid Teas and some of the 

 Bourbons. This division includes the Bourbon, Bengal, Tea, Perpetual Moss, Polyantha, Hvbrid Tea, nvbri-.-*. 

 Perpetual or Remontant, Hybrid Noisette and Rugosa classes. 



In each class some superior varieties for general cultivation will be found printed in CAPITALS. These 

 are commended to inexperienced amateurs, as being of good constitution and the most desirable in limiteo 

 collections. 



Whenever known, we give the raiser's name and the year when the variety was sent out.
