CATALOGUE OF ROSES. 



In the month of May, or so soon as the leaves have pushed forth, the rose caterpillar 

 makes its appearance ; 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 fingers and thumb, so as to crush the caterpillar ; 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, larva, and all such as come 

 at a later date than 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 or disperse them ; but 

 the plants should be well moistened before the hellebore is applied, so that it will re- 

 main. 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 application will, of course, cause the 

 foliage to drop off, but it is the only remedy we know to be efficacious. The red spider 

 very seldom attacks plants in 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. The disease is generally caused by extremes of heat and cold, and by a 

 long continuance of 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 the substance applied 

 will adhere. 



ADVICE TO CORRESPONDENTS. 



1st. All orders should be legibly written out on the order sheet herein enclosed, this 

 will save us much trouble and at the same time prevent mistakes. 



In case budded plants are ordered, state whether we shall send the same varieties on 

 ■own roots, in case we cannot supply them budded. This is necessary where parties 

 ordering have any preference for either mode. When nothing is said lue exercise our 

 best judgment, and if out of budded plants, send those on their oion roots, and '^vice versaJ' 

 Budded plants, however, cannot be sent by mail — they are too large ; they can only go 

 by express. 



2d. To secure fine plants, particularly of the new sorts, it is advisable that orders 

 be sent in as early as possible, as late in the season the strongest plants will have been 

 selected, and the stock of some varieties exhausted. We fill orders in strict rotation. 



3d. Amateurs, in ordering, will do well to leave the selections to us as far as pos- 

 ;sible, but our list is open to all to make their oum selections. Purchasers, however, will 

 please say if they wish us to substitute, in case all the varieties ordered cannot be sup- 

 plied. In such case we always endeavor to send something better, where it is possible, 

 than the kind called for. We do not substitute without being requested to do so, but if out 

 of any sort toe add to the number of the others ordered, unless otherwise directed. 



4th. It is requested that explicit directions for marking and shipping packages 

 accompany each order. All articles are at the risk of the purchaser after being snipped, 

 and if delay or loss occurs, the forwarders alone must be held responsible.
