were taken along with the cuttings, or 

 unless the young stock is subjected to 

 tlie same conditions which brought on 

 the disease in the first instance. Jn 

 our northern latitude, if normal 

 weather conditions prevail, we expect 

 all such diseases as leaf-spot, rust, etc., 

 to disappear during the plants' stay 

 in the field. Your Texas climate, how- 



rooting. Just why they did not root, 

 I am unable to say with any certainty. 

 The temperature you name is too low, 

 but that should only retard the root- 

 ing, if other conditions are right. The 

 watering with the ammonia and copper- 

 as may have had sgme effect, but of that 

 I am not certain. Next time, use tresb 

 sand and water only with clear water.

ever, is quite different from ours. With 

 the intense heat, you would be likely 

 to have trouble after every drenching 

 rain or rainy spell, especially if you 

 took the disease out along with the 

 plants. 



It might be well to defer such dras- 

 tic measures as you suggest until you 

 can see whether or not you will be 

 able to use these young plants for 

 benching this fall. One can never tell 

 what kind of season is in store. 1 

 would suggest that you dust the young 

 plants well with Grape Dust or dry 

 slaked lime. Spraying with Bordeaux 

 mixture should also prove effective in 

 eradicating the disease, or in prevent- 

 ing its appearance if it has not started.

CUTTINGS HAVE NOT BOOTED. 



1 am sending you a few carnation 

 cuttings from a bunch of 3,500 which 

 I made December 20. There are few 

 that are rooted yet and they look 

 wilted, although I have kept the sand 

 quite moist all the time. The temper- 

 ature has been 45 to 48 degrees at 

 night and 50 to 60 degrees in the day 

 time. The first watering after they 

 M'ere put in the sand was with a solu- 

 tion of ammonia ami copperas. They 

 were placed in sand which ha<l been 

 used to root geranium cuttings. There 

 are few of them rotting, but they do 

 not root. Will they root yet an<l why 

 have thev not rooted before this time?

I do not know in what condition the 

 specimens forwarded left your place, 

 but they were dry as a bone when 

 they rea<'hed here. They do not show 

 the least sign of a callus on the lower 

 end and if your cuttings are all like 

 these, there is little prospect of their

 would advise you to buy what cuttings 

 vou need for the coming season.

CUTTINGS RUSTY AND SPOTTED. 



Will you please tell me how to get 

 rid of rust on carnation cuttings and 

 tell me, also, what is the trouble where 

 some cuttings are spotted yellow? 



C. W 



About the only way to get rid of 

 rust on cuttings is to pick it off. If 

 they are not too badly affected, this 



will be sufficient, but if there is a great 

 deal of rust on them, so that after it is 

 all picked off the cuttings are denuded 

 of most of the foliage, then it would 

 be better to throw them away. If you 

 have not a sufficient stock of healthy 

 cuttings, I would advise you to buy 

 what you need from some reliable spe- 

 cialist, rather than try to root them at 

 this late date. When rust attacks cut- 

 tings and is allowed to get a good 

 start, it is difficult to get it under con- 

 trol. Usually the young plants are so 

 weakened by it that they can never 

 become strong plants and would better 

 be discarded at the outset. Picking 

 off the affected leaves and dusting with 

 air-slaked or hydrated lime will keep 

 it in check. 



Those light spots are most likely 

 what we formerly knew as "bacteri- 

 osis " and later as "stigmonose, " both 

 of which names are being proved to be 

 correct in some cases only. Your case 

 may be similar to others which have 

 come under my observation. Perfectly 

 clean cuttings would be taken from 

 apparently clean, healthy plants. After 

 the cuttings had been in the sand 

 about two weeks, these light spots 

 would begin to show. They would be 

 plainly visible until about a month 

 after potting, when the new growth 

 would come as clean again as the plant 

 from which the cutting was taken. I 

 feel confident that no insect of any 

 kind had anything to do with these 

 spots and the circumstances tend to sup- 

 port the theory advanced by me many 

 years ago, that it is a case -of improper 

 nourishment. Avoid such cuttings as 

 much as possible, thereby aiding in 

 the elimination of the trouble.

SOIL FSOM CHICKEN TABD. 



Three years ago I put some soil from 

 the greenhouse into a chicken yard, 

 25 x 50 feet, where about thirty to 

 forty chickens are kept during the 

 year. The soil is about a foot deep in 

 the yard. Can this soil be used for 

 carnations again in the coming fall, 

 without additional cow manure? The 

 soil seems rich, not having been used
