NATIONAL FLOWER SHOW GUAR- 

 ANTEE FUND. 



The following open letter has been 

 sent out by Secretary John Young. 



"Dear Sir — At a meeting of the Na- 

 tional Flower Show Committee of the 

 Society of American Florists and Or- 

 namental Horticulturists held on Oc- 

 tober 1.3-14 last, in St. Louis, the 

 Chairman. Jlr. George Asmus and the 

 Secretary. Mr. John Young, were in- 

 structed to raise a guarantee fund of 

 $10,000 to cover the National Flower 

 Show to be held in St. T^ouis. April 

 6-15, 1918. 



"While the sum mentioned could, no 

 doubt, be raised in and around St. 

 Louis, it was the thought of the Com- 

 mittee that the fund should be na- 

 tional in character and represent 

 every section of the country. The 

 forthcoming show in St. Louis prom- 

 ises to be as successful as the previ- 

 ous National Flower Shows, and it 

 goes without saying that it will result 

 beneficially to the trade at large. 



"Your kind interest in the project 

 m the way of a contribution to the 

 guarantee fund is cordially solicited, 

 hence the inclosure herewith of a con- 

 tribution blank. The guarantors for 

 the last National Flower Show not 

 only were reimbursed to the e.vtent of 

 their actual contributions, but also re- 

 ceived a substantial share of the prof- 

 its eriual to la per cent of the entire 

 amount subscribed. 



"The C^ommittee also would esteem 

 donations of special prizes, the same 

 to be offered under the names of the 

 donors. If you should feel disposed to 

 favor us with the offer of a special 

 prize, kindly, if possible, select the 

 subject for your award from the pre- 

 liminary schedule, thus relieving our 

 obligations to the prize fund to the 

 extent of the value of your donation. 

 The first preliminary schedule is now 

 on the press."

FALL MEASURES TO COMBAT 

 ROSE DISEASES. 



Rose gardeners should take advan- 

 tage of the fall season, says the U. S. 

 Department of Agriculture bulletin, to 

 make their plants as free as possible 

 from disease by methods that cannot 

 well be followed during the growing 

 season. It is true in general that 

 whatever the disease, the affected por- 

 tions of the plants should be cut out 

 in the fall and the shortened bushes 

 sprayed. It is assumed, however, that 

 spraying will not have been delayed 

 until fall, but will have been carried 

 on as a control measure at frequent 

 intervals since spring. The diseased 

 wood removed in the fall, together 

 with the old leaves and debris under 

 bushes, should be burned. In case of 

 attacks by rusts, canker and leaf 

 spots, the diseased wood or leaves 

 should be removed and burned even 

 during the growing season. 



A wholly satisfactory method of con- 

 trol of rose canker has not been 

 worked out. The early symptoms are 

 the appearance of small reddish 

 patches on the green parts, generally 

 of 1-year-oId growth. The disease is 

 caused by a fungus classed as a wound 

 parasite, that is, the spores gain en- 

 trance to the bush through certain me- 

 chanical injuries. These may be slight 

 ones made upon the young branches 

 by the thorns of the bush itself when 

 one branch has been blown against 

 another, or by insect punctures. Such 

 infected areas may increase until the 

 entire stem is surrounded and may 

 extend for several inches along the 

 branch. The only advice to be given 

 is to cut away rigorously all diseased 

 branches, and it may be necessary to 

 cut back entire bushes if badly infect- 

 ed. Cover the exposed surfaces made 

 by this cutting with paint or tar. This 

 diseased material must be burned and 

 the dormant bushes sprayed with 

 strong Bordeaux mixture in both the 

 autumn and early spring. At the first 

 appearance of the disease, cut away 

 and destroy all the branches showing 

 infection. Then spray about every 

 10 days, first with Bordeaux mixture 

 and later with ammoniacal copper car- 

 bonate, as spraying has no disfiguring 

 effect upon the foliage, an appearance 

 to be avoided when blossoming time 

 is near. It is possible that by such 

 careful attention the jilants may out- 

 grow the disease. 



Pruning Climbing Roses 



Special pruning methods must be 

 employed for climbing roses. These 

 methods are determined by more or 

 less of a compromise between the de- 

 sire, on the one hand, to force the 

 growth of blossom-bearing, new wood 

 4jy removing old wood, and, on the 

 other hand, the desire to keep arbors 

 and similar structures at least jjartial- 

 ly covered. One-half of the wood 

 should be pruned from all the climb- 

 ers, as from the other types of roses, 

 at planting time. In the case of the
