yellow color. They also enlarged and 

 elongated. The epidermis over the 

 younger spots remained unbroken and 

 the leaf was normal, but later the tis- 

 sue beneath these areas collapsed and 

 soon the epidermis became yellow and 

 broken. As a result of these many 

 diseased areas, the leaf often wilted 

 and shriveled up. At first this was 

 thought to be the disease known as 

 "stigmonose" or "bacteriose," but 

 samples of the plant sent to the au- 

 thority who worked out the cause of 

 the above disease, brought the answer 

 that it was not the same disease. Fur- 

 ther observation on these plants reveal 

 the fact that many of them had been 

 attacked by red spider, but whether 

 this was the cause of this peculiar 

 disease or not we will not attempt to 

 say at this time. We attempted to 

 transfer this disease to other plants, 

 but failed. No fungus or bacterium 

 could be found associated with it. Cut- 

 tings from plants so affected died be- 

 fore they had a chance to form roots. 

 Another disease sent me by a well 

 known florist has been received from 

 two other sources since. The carna- 

 tion plants suffering from this disease 

 have an unusually large stem from the 

 branches down and there are often 

 swellings or tumors — rough, wart-like 

 bodies arising from the stem near the 

 surface of the ground. These tumors 

 remind one of the galls in the disease 

 known as the crown gall. But not all 

 plants have these galls, although af- 

 fected by this disease. The roots of 

 these plants are unusually large and 

 stalky, but when broken they reveal a 

 brown rotted area in the center which 

 extends from the end of the roots up 

 to the main stem. A cross section of 

 the stem also shows a brown rotted 

 area beneath the bark and often ex- 

 tending well into the wood of the stem. 

 The cause of this disease was not de- 

 termined, since at the time of receiv- 

 ing these specimens our laboratory was 

 not yet equipped with apparatus neces- 

 sary for this sort of work. 



Material Wanted for Study. 



The two diseases of carnations given 

 above are of especial interest to us, 

 since they have never been described, 

 and they may later become of great 

 economic importance to the carnation 

 growers of the state. For this reason 

 we would appreciate material or in- 

 formation concerning these troubles. 

 Especially would we like some plants 

 sent to us suffering from either of the 

 above diseases.

Diseases of various other plants have 

 been given attention in our laboratory, 

 but for the most part these have been 

 either local or well known diseases, 

 and we have answered inquiries con- 

 cerning them by letter. A disease 

 of palm (Kentia Belmoreana), due to a 

 fungus called Gloeosporium, which 

 caused a rotting oflf of the plant at the 

 surface of the ground, was of especial 

 interest. 



Our laboratory is now fully equipped 

 and we desire material of all sorts from 

 the florists of the state. Our desire is 

 to become acquainted with your 

 troubles, and although we cannot prom- 

 ise instant relief we hope to be able to 

 give you definite information upon 

 which you can depend. All material 

 sent to us should be packed in the 

 same manner you would prepare cut 

 flowers for shipment. We concern our- 

 selves only with diseases due to fung- 

 ous attacks, but plants will be exam- 

 ined and if we believe the trouble is 

 due to insects we will place the mate- 

 rial in the hands of the entomologist, 

 who will answer your inquiries. Mate- 

 rial may be sent by express at our ex- 

 pense. The address is Floricultural Ex- 

 periment Station, University of Illinois, 

 Urbana, 111. Pack plants to arrive in 

 a frjsh condition. 



AN INDIANA PLANT. 



The middle west is becoming thickly 

 dotted with prosperous establishments 

 of moderate size, catering to the whole- 

 sale and retail demand, a typical one of 

 these being shown in the accompanying 

 illustrations. This is the range of the 

 Dille Floral Co., of Greensburg, Ind. 

 The business was built up through the 

 joint efforts of J. L. Dille and his wife, 

 but Mrs. Dille died February 3, leaving 

 Mr. Dille not only with the care of the 

 plant but also with two small children. 

 A married daughter, Mrs. Max Bardoch, 

 lives at 1306 Granville avenue, Chicago. 



The range consists of four up-to-date 

 houses each 27x145, a violet house on 

 the north 6x75, and a propagating house. 

 The range is heated by a No. 13 Kroe- 

 schell boiler with the threaded boiler 

 tube system of piping and a generator 

 to put the water under pressure. The 

 property, which directly adjoins the city 

 limits, consists of twenty acres of fine 

 soil. The principal crop is carnations, 

 with a few roses, violets and some early 

 mums. 



In the interior view of one of the 

 houses Mr. Dille is seen in the center 

 walk. At the left is W. C. Konzelman, 

 the grower, and in front of him is his 

 son. Evert Konzelman. At the right of 

 Mr. Dille is F. Brightbill, who looks the 

 part.
