feet a cure by external applications; 

 that is why the Bordeaux and the nico- 

 tine had no effect on the disease. Keep 

 the soil a trifle on the dry side and 

 avoid fertilizers that will tend to pro- 

 duce a soft growth, such as liquid cow 

 manure, sheep manure, nitrate of soda, 

 etc. Use more lime and bone meal, if 

 your plants really need feeding. 

 Toward spring you can use a liberal 

 manure mulch without harmful results.

CATCH SNAILS AT NIGHT. 



Large snails have made their home 

 in three or four of our carnation and 

 sweet pea benches. They chew every- 

 thing in sight. We have tried nicotine 

 exiraet, Slug Shot — in fact, everything 

 we could think of — without results. Do 

 you know of an effective exterminator?

If you have tried all the forms of 

 poisoned bait without effect, the only 

 remedy left is to pick the snails by 

 hand. As they feed at night, you will 

 have little difficulty in> catching them, 

 if they are the large kind. Get a 

 strong bull's-eye lantern and go along 

 the beds where they are in the habit 

 of feeding, and you will be able to 

 pick them up and destroy them. Be- 

 fore resorting to this, I would suggest 

 that you try spraying the plants thor- 

 oughly with arsenate of lead.

CASE OF CARNATION YELLOWS. 



I am sending you some carnation 

 leaves that seem to be badly affected 

 with some disease. The trouble started 

 several weeks ago and is spreading 

 rapidly. Kindly inform me what the 

 disease is and give a remedy for it. 



F. F. 0.— 0. 



Your carnations are troubled with 

 the disease called carnation yellows. 

 The cause of this disease is not defi- 

 nitely known and no effective method 

 of control as yet has been worked out. 

 The American Carnation Society has 

 taken the matter in hand and a solu- 

 tion no doubt will be reached in due 

 time. For the present, I suggest that 

 you follow a moderate course in your 

 culture. Avoid anything that will tend 

 to produce a soft growth. Eun the 

 soil just a trifle drier than you ordi- 

 narily would and give the plants plenty 

 of ventilation, along with a cool tem- 

 perature. Avoid those fertilizers that 

 are high in nitrogen until the sun gets 

 stronger, towards spring. 



This disease always is worse during 

 the dull winter months than in the 

 early fall, when the sun is stronger. 

 When propagating avoid those plants 

 which show much of this disease, be- 

 cause, while the young shoots may not 

 show much of it and the plants may 

 seem to outgrow it in the summer, the 

 disease surely will reappear the next 

 winter. A. F. J. B. 



ROSETTE, WONDER, BEACON. 



I am sending you under separate 

 cover some carnation blooms and would 

 like to have you tell me the cause of 

 their condition. The flowers have the 

 appearance of being burned around the 

 edges. Some of them open fully, but 

 others appear sleepy and do not expand 

 completely. The plants are grown un- 

 der the approved treatment and seem

healthy and strong. Rosette is affected 

 more than any ox the other varieties, 

 with White Wonder next and then. Bea- 

 con. Enchantress Supreme seems to 

 have escaped the trouble. 



G. I.— 111. 



I regret to say that I cannot tell you 

 positively what is the cause of the 

 blooms coming in that crinkled condi- 

 tion. We have always held that it is 

 caused by a loss of vitality in thie stock. 

 You usually will find that a plant which 

 throws one of these blooms will give no 

 perfect blooms. All will have that same 

 crinkled appearance to a greater or 

 less degree, and one of these plants 

 may stand among a lot of perfectly 

 good ones. Rosette showed this fault 

 all the time we grew it and White Per- 

 fection developed it during the last year 

 or two. White Wonder has never shown 

 it with us, nor has Beacon, except when 

 a plant was badly affected with the yel- 

 lows. I would suggest that you change 

 your stock of the varieties thus affected, 

 as the simplest means of escaping the 

 evil. A. F. J. B. 



PRIMULA FOLIAGE WHITE. 



Can you tell us what causes the foliage 

 of our Primula obconica plants to turn 

 white! We have changed the soil and 

 location in the greenhouse, but as yet 

 have been unable to find out what 

 causes this condition. We have one 

 bench of these plants on which the foli- 

 age is almost white. 



M. F. C— Colo. 



The fact that a whole bench is af- 

 fected in the same way would go to 

 show that some soil condition is the 

 cause of this trouble. Probably the soil 

 is too sour. Without knowing just what 

 your compost is, it is hard to give an 

 opinion. A compost of well decayed, 

 fibrous loam, two-thirds, and equal parts 

 of leaf -mold, not too much decayed, and 

 well rotted manure, with a little sand 

 added, makes an ideal mixture for 

 Primula obconica. If your plants are 

 heavily rooted and perhaps starved, try 

 weak doses of nitrate of soda or Clay's 

 fertilizer in water, at intervals of a 

 week. C. W.
