COLLEGE THIS WINTER. 



It you have wanted to go to college, 

 but have never completed a high school 

 course, here are two excellent oppor- 

 tunities for you. Ohio State Univer- 

 sity at Columbus offers a three-year 

 course which opens Tuesday, Oct. 16th 

 and closes March 1.5th. In the allotted 

 time a well rounded education can be 

 obtained. The work is adapted to the 

 horticulturists, the florist and the nur- 

 seryman; besides the fundamentals in 

 science, courses are given in English, 

 soils, fertilizers, insects and the prac- 

 tical courses in vegetable gardening, 

 fruit Rrowing, floriculture and land- 

 scape gardening. An opportunity is 

 given the students to avail themselves 

 of the advantage of military drill. 



The eight weeks winter course open- 

 ing Jan. 7 will give those persons a 

 chance to attend college who cannot 

 spare the full three years. A word in 

 regard to the cost of taking such a 

 course may not be out of place. The 

 tuition is free. Energetic students 

 have excellent opportunities to wait on 

 table for their board so that the time 

 spent in Columbus should not be very 

 expensive. It is estimated that a stu- 

 dent can go through the eight weeks 

 winter course for $58. Address the 

 College of Agriculture, Ohio State Uni- 

 versity, for the catalogue which will 

 explain all about these courses. The 

 three year courses open October 16tlj.

BLIGHT ON HELIOTROPE. 

 Editor IbinTirri.TUKi;: 



I note Irom your edition of Septem- 

 ber 2i)th. "H. E. C." of Ohio asks in- 

 formation regarding the cause of and 

 remedy for blight on plants of helio- 

 trope growing both in the greenhouse 

 and outside. 



In answer to tliis iiuiuiry it was sug- 

 gested that Thrip .Iiiice No. 2 or whale 

 oil soap be used. This would hardly 

 be possible, as both tlie remedies sug- 

 gested are insecticides — not fungicides. 

 The disease or blight of the heliotrope 

 is caused by a fungus called septoria. 

 There are over nine liundred species, 

 all parasitic, several of them of econ- 

 omic inii'ortancee, but most of them 

 occurriiis on non-economic hosts. S. 

 pisi is often found on the foliage and 

 pods of lale-grown edible peas as well 

 as on the foliage of sweet peas. S. 

 piricola is found on trees of pears and 

 apples: S. fragariae on the straw- 

 berry; S. antirrhini attacks the snap- 

 dragon severely; S. chrysanthemella 

 is prevalent in some sections on the 

 chrysantlionium, both on the cuttings 

 as well as on the leaves of old plants. 



The writer would recommend one or 

 the other of the following remedies to 

 be applied to the plants or cuttings in 

 order to check the spread of the dis- 

 ease as well as to clean up the spores 

 during the stage when they are being 

 transmitted from one plant to another. 



CUPRAM. 

 Copper Carbonate, IVi ounces. 

 Cominirflal Ammonia (strong). 16 ounces. 



liquid. 

 Water to make 10 gallons. 



In preparing the fungicide, dilute 

 the ammonia with ten parts of water 

 and shake it up with the carbonate 

 until this is dissolved; afterwards add 

 the rest of the water. Spi^y the foli- 

 age of the plants occasionally through- 

 out the season with this mixture. 

 Bordeaux mixture may be used, form- 

 ula 4-4-40, but on account of a lime de- 

 posit left on the foliage after spraying, 

 this is somewhat objectionable. 



If "H. E. C." of Ohio would send in 

 specimens of the plants affected with 

 the disease, we will be glad to give 

 him information regarding the species 

 and life history of the disease.
