to us that we may be killing friends 

 instead of enemies, so we send it to you 

 for information. We cut the head oflf 

 so that it would not suffer in transit, 

 but you will find the head wrapped in 

 paper with the body L. M. S. 



The insect in question is nothing else 

 but our old friend the katydid. Whether 

 the katydid does any harm to chry- 

 santhemums, is a question that I cannot 

 answer definitely, but I will say that in 

 my experience I have never found that 

 it has, 60 I do not think that L. M. S. 

 need worry over this forerunner of the 

 fall season. Chas. H. Totty. 



A SPOET OF TOUSET. 



Please let me know whether a pure 

 yellow sport of the Mme. C. Touset 

 chrysanthemum has ever been intro- 

 duced to the trade. H. E. 



So far as I am aware, no yellow sport 

 of Mme. C. Touset has yet been intro- 

 duced to the trade. If H. E. believes 

 he has a sport' of that kind in his pos- 

 session, he should be careful to see that 

 it is a true sport and not something 

 else mixed in with his stock. The fo- 

 liage should be identical with that of 

 the parent in order to guarantee its 

 being right. Chas. H. Totty. 



LEAF-SPOT ON MUMS. 



Enclosed you will find some diseased 

 leaves of mums. Please tell us the name 

 of the disease, the cause and the rem- 

 edy. They are grown in pots, in good, 

 rich clay loam, with a little sand and 

 bonemeal. The benches are covered 

 with coal ashes, mixed with a small 

 proportion of wood ashes. The house 

 has been rather damp until lately, when 

 we have had steam at night. The weath- 

 er has been varied, but rather warm 

 for this time of year. The dis- 

 ease showed first on Golden Glow, and 

 the other early kinds are now nearly all 

 affected more or less. J. F. W. 



The leaves, on arrival, were badly 

 wilted, but, so far as I could see, they 

 were affected by leaf-spot. The leaf- 

 spot is nearly always present in the 

 chrysanthemum, and when, as frequent- 

 ly happens in the fall, the foliage gets 

 crowded by the excessive growth, the 

 spot will almost invariably start on the 

 ■plants. It is a fungoid disease and 

 spreads from leaf to leaf where condi- 

 tions are favorable for its development. 

 The best remedy I know of is sulphide 

 of potassium, used in the proportion 

 of one ounce to two gallons of water 

 and sprayed directly on the under side 

 of the leaves. This, as a general rule, 

 provided the houses are run dry, great- 

 ly reduces the seriousness of the trou- 

 ble. Chas. H. Totty. 



INSECTS ON MUMS. 



We are having trouble with our 

 mums. On the under side of the leaves 

 there are lots of small green worms 

 which are invisible to the naked eye, 

 but are eating the under surface and 

 the edges. There is, or was, a large 

 worm on the inside which forms like a 

 sack, and the spot has a watery brown 

 appearance and is about the size of a 

 nickel. 



The leaf is much drawn up and has 

 all the appearance of red spider. The 

 under side has a reddish appearance, as 



Chrysanthemum Unaka. 



if scalded. The outside is curved down 

 and is marked with a few grayish 

 specks, such as are made by the spider. 

 I find also that a number of plants 

 have a fine network of web, but can see 

 only a few of what I think are small 

 red spiders, and some black ones. Will 

 this spider, if it is red spider, do much 

 harm? Will it be especially harmful 

 when the mums come into bloom? How 

 can I best get rid of these two pests? 



K F. C. 



K. F. C. seems to have a variety of 

 insects that are causing trouble on his 

 chrysanthemums. The large worm de- 

 scribed as on the inside of the leaf is 

 apparently the same as that which at- 

 tacks celery, Tephritis onopordinis. This 

 worm eats out all the center of the 

 leaf, leaving merely the outside skin. It 

 is almost impossible to get rid of it, ex- 

 cept by hand picking, because any solu- 

 tion that is strong enough to pierce the 

 skin and reach the worm is strong 

 enough to cause serious injury to the 

 foliage. 



The leaves having a fine network of 

 web are undoubtedly covered with 

 spider. I do not know how close the 

 relationship is between the spider and 

 thrips, but there is a tiny black insect 

 and also a dirty white one, which are 

 sometimes called spider and sometimes 

 thrips, and both of them work in the 

 same way as the red spider. If these 

 are bad on the plants. K. F. C. will 

 get but few flowers this fall that will 

 be perfectly finished. When syringing 

 is discontinued, these insects multiply 

 rapidly, and the web extends up from 

 the leaves to the outside petals. The 

 various forms of tobacco do not seem to 

 be of much avail against these insects. 

 If K. F. C. is still able to do it, there 

 is nothing better than vigorous spraying 

 from the hose, with a fine nozzle at- 

 tached to the end like a Stott nozzle, 



and washing every leaf thoroughly on 

 the under side. Chas. H. Totty. 



SMITH'S NEW MUMS. 



The firm of Elmer D. Smith & Co., at 

 Adrian, Mich., can be counted on for 

 a set of new chrysanthemums as regu- 

 larly as the autumn comes around, and 

 the growers who have profited through 

 their introduction of Golden Glow will 

 be interested that this year Smith & 

 Co. have both an early white and an 

 early pink. Smith's Advance, the 

 white, was illustrated in The Review 

 of September 8, and an illustration 

 herewith shows Unaka, the October 

 pink. Buds taken between August 1 

 and 15 not only give fully developed 

 blooms in sixty days, but are said by 

 the originator to be superior to earlier 

 or later buds when color and fullness 

 are considered. It is a broad petaled 

 Japanese incurved variety, of large size 

 and much depth for so early a sort. 

 Mr. Smith describes the color as inter- 

 mediate between Rosiere and William 

 Duckham. It is a seedling from Octo- 

 ber Frost, which is an easy doer under 

 all sorts of growing conditions. From 

 early May benching the plants attain a 

 height of four feet. When exhibited 

 before the Chrysanthemum Society's 

 committee on seedlings at Cincinnati, 

 October 8, it was scored ninety points. 



The Smith concern appears to be 

 working toward earliness on its new 

 mums, for Chrysolora, another of its 

 present season's offerings, is described 

 as an early Col. Appleton — fifteen days 

 early. The color is between Appleton 

 and Bonnaffon, and Mr. Smith considers 

 this variety one of his greatest achieve- 

 ments. When exhibited at New York 

 October 15 it scored ninety three points, 

 and on the same date made ninety-four 

 points at Cincinnati.
