AMERICANS ABROAD. 



The behavior of American carnations 

 in England is not a matter of import- 

 ance to growers here, but it neverthe- 

 less is of interest to note how they 

 do under other conditions. The follow- 

 ing notes are by Allwood Bros., of 

 Hayward's Heath, Sussex, England: 



"Of last season's American novel- 

 ties, Bosette is considered the best in 

 England. It is not so free flowering as 

 many varieties, but the color is won- 

 derfully bright and solid. 



"St. Nicholas is not considered so 

 good as Scarlet Glow in any respect, 

 the flowers being too thin. 



"Benora is all that was claimed for 

 it and has done well over here. Un- 

 fortunately, the flowers are not popular 

 in Coveht Garden Market. 



"Wodenethe produces some fine flow- 

 ers, but it is not considered so good 

 for market as White Wonder or White 

 Enchantress. 



"Brooklyn comes bad over here; the 

 color has too much magenta in its make- 

 up and in productiveness it is a long 

 way behind Mrs. C. W. Ward." 



TWO SIMHiAE INQUIRIES. 



I am sending you under separate 

 cover some shoots of White Enchant- 

 ress that are yellow at the tips. The 

 plants are growing rapidly and, aside 

 from this discoloration, they appear 

 to be healthy. The house has been run 

 cool, with a temperature of 48 to 50 

 degrees at night, or practically that. 

 The plants are in solid beds and have a 

 large number of shoots like the en- 

 closed. I am a new man in the busi- 

 ness and any information will be most 

 gladly received. E. G. C. 



Will you kindly explain what causes 

 the leaves of White Enchantress to 

 turn yellow? You will find samples en- 

 closed. H. V. 



The specimens forwarded by E. G. 

 C. showed plainly the cause of his 

 trouble. I think there is no question 

 that it is a bacterial disease, but just 

 how to proceed against it I am unable 

 to say. In a recent discussion by ex- 

 pert carnation growers, the fact was 

 brought out that the whole Enchant- 

 ress tribe is affected by the malady 

 that E. G. C. complains of. In the 

 spring these yellow tips appear without 

 any apparent cause, and the trouble 

 seems to be general all over the coun- 

 try. Some think it indicates a weak- 

 ening in the strain, and perhaps they 



are right. Others think it is caused 

 by overfeeding, but experience does 

 not bear out this latter theory. I am 

 rather inclined to the opinion that it 

 is aggravated by heavy watering with- 

 out sufficient nourishment being given 

 along with it. That, however, is 

 merely a theory which I have not as 

 yet tested out. If E. G. C. cares to 

 do so, I would advise that he proceed 

 with that theory in mind. 



In reply to H. V., I would say that 



if the leaves forwarded by him for in- 

 spection were taken from his blooming 

 stock, he will find his answer in the 

 preceding paragraph, replying to E. G. 

 C. If they were taken from his young 

 stock, then my advice would be to 

 dump every plant that shows these 

 yellow leaves. They may apparently 

 outgrow the trouble during the summer, 

 but it will show up again next winter, 

 just as sure as winter rolls around. 

 The only effective way to get rid of it 

 is in selecting the cuttings and culling 

 out the plants from time to time as the 

 disease appears among them.

RUST AND SPOT DISEASE. 



I am sending you some carnation 

 sprays, which seem to be affected by 

 two different diseases. Can you tell 



me what is the matter and what to do- 

 to remedy the trouble? L. M. S. 



The disease on one of the specimens 

 forwarded is the common carnation 

 rust. Unless your plants are badly af- 

 fected, this disease should give you lit- 

 tle trouble from this time on. Too much 

 moisture and too little ventilation are 

 usually the cause of this disease getting 

 started. Some also claim that an ex- 

 cessive supply of nitrogen in the soil 

 will bring it on. However, if you will 

 water and ventilate carefully, you will 

 have little trouble with rust. Dusting 

 the plants with Grape Dust will help ta 

 keep it away. 



The other is a spot disease, which 

 can be controlled by spraying with. 

 Bordeaux Mixture. Cut away the worst 

 affected shoots and spray once or twice 

 each week until the trouble disappears. 

 There should be little difficulty in con- 

 trolling this disease, now that bright,^ 

 warm weather is due. A. F. J. B. 



PRIMULA AND COIN. 



Henry Schmidt, of Union Hill, N. J.,, 

 who is well known as a primula spe- 

 cialist, supplied the photograph from 

 which the accompanying illustration was 

 prepared. It shows a Primula obconica 

 flower in comparison with a coin the 

 size of a silver dollar. As it is against 

 the law to photograph United States 

 money, Mr. Schmidt used a foreign coin, 

 the German 5-mark piece, the equiva- 

 lent of our silver dollar, one and one- 

 half inches in diameter. Mr, Schmidt 

 grows all the popular market primulas 

 and has worked up his own special 

 strains of each. 



DIRECTION OF HOUSES. 



I intend to build a range of green- 

 houses this summer. The range will 

 consist of four houses, each 29x200. 

 As there is a gentle slope toward the 

 northwest, I intend to run the houses 

 north and south, to avoid having the 

 office in the rear. Do you think such 

 a plan is advisable in this part of the 

 country? My location is central Mis- 

 souri. C. A. C. 



The letter states that it is proposed 

 to run the houses north and south, 

 which is generally understood to im- 

 ply that the direction of the ridge, or 

 greatest length of the house, is north 

 and south, but the accompanying 

 sketches show two different plans with 

 regard to this point. In plan No. 1 

 the ridges run east and west, with the
