is the best preventative. For disposing of the ever-present 

 aphis, or black fly, fumigation with tobacco has proved the 

 surest and cheapest remedy. Throughout the year chrys- 

 anthemums should be subjected to a weekly fumigation, the 

 prevention of insects being especially desirable in their suc- 

 cessful management. 



About forty varieties of chrysanthemums are grown in the 

 college greenhouses, many of them represented by a few 

 plants only, to ascertain their merits for such a trade as ours. 

 This method of becoming acquainted with newer varieties 

 should lie adopted by all progressive florists. The fact re- 

 mains, however, that many older varieties have not yet been 

 superseded. Not infrequently the size of bloom has been 

 the principal point in favor of the newer introductions, 

 sacrificing in some instances their purity of color. 



The following varieties have proved themselves well 

 adapted for a local trade, being easily grown and naturally 

 vigorous. In their order of flowering they are : white, — 

 Polly Rose, Ivory, Alice Byron, Queen, Timothy Eaton, 

 W. H. Chadwick, Merry Christmas ; pink, — Glory of the 

 Pacific, Pink Ivory, George Carpenter, Mrs. Perrin, IVIrs. 

 C. F. Berwind, Mrs. S. T. Murdock, Maud Dean ; yellow, — 

 Sinclair, Robert Halliday, Colonel Appleton, Major Bon- 

 afibn, W. H. Lincoln, W. H. Reiman ; bronze, — Brutus, 

 Sunrise, Petaluma ; red, — Gettysburg, Malcome Lamond, 

 Cullingfordii. The varieties that do well as pot plants are : 

 Ivory, Alice Byron, Pink Ivory, Mrs. Perrin, Mrs. S. T. 

 Murdock, Mrs. C. F. Berwind, Sinclair, Major Bonafibn, 

 W. H. Lincoln, Brutus, Sunrise, Cullingfordii. 



The singles and pompons should not be overlooked. They 

 may be grown in pots with very little disbudding. They 

 have a wide range of colors, and make salable pot plants ; 

 the white ones afford good material for designs, etc. Among 

 the best may be mentioned Snowdrop, President, Julia 

 Lagravere, Queen of England, Mizpah, Buttercup. 



A great aid in the matter of testing the qualifications of 

 varieties is the use of the " scale for judging" adopted by 

 the Chrysanthenmm Society of America. In scaling a va- 

 riety a searching investigation is made, and many defects are
