cheaper, but the difference is not com- 

 mensurate with the difference in quality. 

 Some diflBculty is experienced in know- 

 ing whe^ the stock received is of pure 

 strain. If ezimium and multiflorum are 



mixed, the only difference in plants and 

 blooms is one of quality. Multiflorum 

 is only a better quality than eximiura, 

 and the variation is laid to poor bulbs.

with tobacco in any of its forms is sure 

 to injure the buds, having a very delete- 

 rious effect on tae color of the petals. 

 Consequently our most strenuous efforts 

 should be put in force before the crop 

 matures. Bibes. 



BLACK SPOT. 



What is the matter vritie my rosea? 

 The leaves become covered with black 

 spots and fall off. I have the plants in 

 4-inch pots, and want to use them for cut 

 flowers next winter. They were in this 

 condition when 1 received them. What 

 shall I do for the disease! P. J. K. 



BEAUTIES. 



Treatment for Young Stock. 



When young Beauties have attained a 

 length of twelve or fifteen inches and 

 are forming buds, if they are strong 

 they should be cut back, taking off three 

 of four of the topmost eyes. This will 

 divert part of the strength into the 

 lower eyes, causing them to break and 

 form a more bushy plant. 



There being nearly always a demand 

 for Beauty buds, the temptation to mar- 

 ket them as early as possible is fre- 

 quently the cause of giving the young 

 plants a stunted habit, from which it 

 takes them a long time to recover. De- 

 nuding the plant of so much of its 

 breathing apparatus causes a check to its 

 growth, the wood hardens and ripens 

 prematurely and there it remains till 

 cool weather sets in. Beauties, to give 

 good results in winter, should not also 

 be expected to give a large cut during 

 summer or early fall. 



During recent years and particularly 

 in some localities the worst trouble that 

 Beauty growers have had to contend 

 with, and which still keeps them guess- 

 ing, has been the pest called thrips. This 

 insect has caused more loss and damage 

 to Beauty crops than all the other trou- 

 bles combined. At this season the grow- 

 er should keep a sharp lookout for these 

 pests, so that they may not secure a 

 lodgment among the young stock. Be- 

 fore the plants begin to bear a crop the 

 insects give little evidence of their pres- 

 ence, and it requires a sharp and prac- 

 ticed eye to read the signs, but as soon 

 as the buds begin to develop, their work 

 becomes manifest to even the most inex- 

 perienced. 



While infesting all varieties of roses, 

 thrips commit their greatest destruction 

 among Beauties under glass, and to 

 houses containing this variety the grow- 

 er should direct his best efforts and at- 

 tention. 



There are many species of these pests, 

 some of them natives and many of them 

 imported, and they are all inimical to 

 rose culture under glass. The imported 

 varieties are quite as destructive as their 

 native congener. They are all so nearly 

 alike as to make it hard to distinguish 

 them, but as their habits and food plants 



are so much alike and the inotliods of 

 extermiaating them so similar, the grower 

 does not need to spend his time in deter- 

 mining their identity. 



Ftevention being so much better than 

 cure in this case, rigid precaution against 

 increase in, and in proximity to, rose 

 houses, and their introduction into the 

 houses among such materials as soil, 

 manure, litter, etc., should be in force 

 the whole summer and fall. Keeping the 

 ground near the houses and in the vicin- 

 ity of soil piles clear of weeds is one 

 of the best preventives. 



If the weeds have been neglected they 

 should now be cut down and burned. It 

 is also a good plan to burn the grass and 

 ground herbage near the houses during 

 a hot spell. Weeds in the houses, on the 

 paths, and underneath the benches should 

 be strictly kept down, as these afford 

 both feeding ground and shelter. 



During the growing season and while 

 we are practicing disbudding is a favor- 

 able time to apply the remedies, as we 

 can use more radical measures then than 

 we can apply with safety or prudence 

 after we allow the crop to come. 



After crops begin to show color the 

 means of destroying these pests become 

 more limited, as persistent fumigating 



This is a genuine case of black spot, 

 and no doubt has been brought about by 

 allowing the plants to become pot-bound 

 and then overwatered. 



Plant out in a bench, giving about one 

 foot of space, and using a compost of 

 four parts good, rich, loamy sod to one 

 of decomposed cow manure. Allow 

 plenty of drainage, give plenty of water 

 and free ventilation night and day, and 

 pick off all affected leaves. The trouble 

 will soon disappear. Eibes. 



NUMEROUS ROSES. 



A very full catalogue of rose names 

 has just been issued in Paris and serves 

 to show how great is the number of 

 varieties. The names of all known 

 roses, or at least of more than 11,000 

 of them, are arranged alphabetically. 

 Concise details are given relating to 

 the section to which each belongs, the 

 name of the raiser, the year of pro- 

 duction, the color of the flowers and the 

 synonymy. Some idea of the numbers 

 of varieties dealt with may be gleaned 

 from the fact that hybrid perpetuals 

 number 2,791, teas 1,434, provins 1,713, 

 hybrid teas 473, polyantha 207. A list 

 is given of the varieties issued each 

 year from 1800, when there was one 

 only. In 1833 none was added to the 

 list. In the year 1905 thirty-three addi- 

 tions were made. In 1901 no fewer than 

 169 new names were launched. Vibert, 

 of Angers, is credited with 600 intro- 

 ductions, a far larger number than any 

 other raiser. 



PINCHING SPECIMEN PLANTS. 



The end of the third week in July is 

 late enough for the last stopping of 

 specimen plants, or for the general run 

 of pot plants that may be planted out 

 for the time being, and which it is pur- 

 posed to take up later and pot, and have 

 produce a dozen or so flowers. 



Ivory and other growers of like deli- 

 cate habit and constitution should not 

 be pinched so late as the stronger ones, 

 and they need more care in watering 

 when a whole lot of mixed varieties are 

 growing together. The man behind the 

 hose can make or mar a good lot of 

 stock in a few days by sheer carelessness, 

 unless he uses common sense in his water- 

 ing, but the same applies almost as 

 strongly to other crops. 



Routine Work. 



General work in the houses now con- 

 sists largely of routine work, staking 

 plants, tying them up, and keeping the 

 beds sweet and free from weeds by a 

 weekly stirring up. It pays to examine 

 the under side of the foliage once in 

 a while. Many a stray brood of cater- 

 pillars can be picked up this way, and 

 one can also see where red spider begins 

 to get in its work. 



-^oout every two weeks get a sprayer 

 that will get right under the foliage, 

 and wash every leaf on the under side. 

 The top side of your foliage may be 

 perfectly clean while on the under side 

 you may find whole colonies of insects. 

 The instinct of self-preservation teaches 

 them early that they arc not nearly so
