way; put a small teaspoonful of carbon 

 in each hole, covering the holes at once. 

 The carbon will not hurt the plants. Do 

 not use any naked light while using it, 

 owing to its explosive nature, Of course 

 the carbon will not destroy any un- 

 hatched insect eggs. C. W. 



A NEW BEAUTY GBOWEB. 



The average grower can make more 

 money from some other crop than he 

 can make from American Beauty roses, 

 80 that special interest attaches to every 

 new man who turns up with a special 

 facility for handling this greatest of 

 all roses. Peter Morgen appears to be 

 such a man; at least he has been so 

 successful with the Beauty in his years 

 as an employee that when he started 

 in business for himself last spring he 

 chose to specialize on the one variety 

 and now has done so well that it is 

 planned to put up four additional 

 houses next season and plant them all 

 to Beauties. 



Mr. Morgen is a graduate of the 

 school of rose growing conducted by 

 Wietor Bros., Chicago. He went to them 

 as a green hand and spent six years 

 in their employ, taking a year for a 

 trip to California after he had four 

 years of training and returning for a 

 postgraduate course of two years. Then 

 he spent eight months with the South 

 Park Floral Co., New Castle, and in 

 the spring of 1911 went to Hunting- 

 burg, in southern Indiana, where he 

 went into partnership with a Mr. Seu- 

 bold and put up two houses, each 24x 

 300. These were up and ready for 

 planting May 24. The illustration is 

 reproduced from a photograph made 

 Thanksgiving day. The success thus far 

 made is such that plans are being made 

 for the addition of four more houses, 

 each 24x300, to be put up early in the 

 spring of 1912 and planted entirely to 

 Beauties. 



Mr. Morgen is particularly proud of 

 the heating system in his two houses. 

 He put it in himself and does not claim 

 it can not be beaten, but says, "You 

 got to show me." He uses steam with 

 the Morehead double trap system, one 

 condensation trap and one trap above 

 the boiler. The addition next spring 

 will call for another boiler. 



SPOTS OX ROSE FOLIAGE. 



Enclosed you will find some rose 

 leaves affected with small, round, black 

 spots. I mulched my roses with fresh 

 cow manure two weeks ago, and since 

 that the trouble started. All my ma- 

 nure was covered two inches with loam. 

 I do not know if it is a scale, as all 

 the woodwork, the glass and even such 

 other plants as poinsettias and lilies are 

 covered with hundreds of those little 

 spots, not as large as a pinhead. Under 

 my microscope it appears formed like a 

 scale, yellow brown underneath, but 



when scraped off with the fingernail, 

 it leaves no typical light spot, as will 

 other scale. I also notice many little 

 flies among the plants, the same as in 

 cow manure. I sprayed with whale oil 

 soap and with nicotine, but without re- 

 sult. Would cayenne pepper hurt the 

 plants, as gardenias, Harrisii lilies and 

 poinsettias? I would be thankful if 

 I could get special advice, as it is rapid- 

 ly increasing. H. K. 



These are not scale or insects, but 

 are not uncommon when fresh cow ma- 

 nure has been used as a mulch. The 

 insects which come with or breed in 

 the manure are the cause of the spots, 

 and their excrements will be found, as 

 you state, on every class of plants, as 

 well as on the woodwork. While fumi- 

 gation will destroy such as are on the 

 wing, others are daily coming into life 

 and will continue the spotting while 

 the freshness of the manure lasts. The 

 pests will soon run out, or they proba- 

 bly have by this time. Be careful in 

 the future not to use the manure too 

 fresh, as in addition to causing these 

 specks on the foliage from insects, the 

 strong ammonia is liable to cause burn- 

 ing of the foliage. It would be unwise 

 to use any strong fumigant, as poin- 

 settias will not stand it, although gar- 

 denias and lilies would. You can kill 

 all insect life in your soil or manure by 

 using carbon bisulphide. Have holes 

 twelve to eighteen inches apart each 



AMERICAN ROSE SOCIETT. 



The members of the American Rose 

 Society seem to be alive to the ap- 

 proaching exhibition and annual meet- 

 ing, to be held this year in January. 

 It is a little earlier and a little differ- 

 ent from heretofore. From information 

 now in hand, it would seem that there 

 is going to be a fine spread. Robert 

 Pyle, of West Grove, will give some 

 evening an illustrated talk concerning 

 his visit to England last June. 



Another matter of interest is in re- 

 gard to the name of the Double Im- 

 proved White Killarney, which was filed 

 with the American Rose Society and 

 which exhibit took prize and recogni- 

 tion at Boston, but, owing to confusion 

 in name and upon request of various 

 people, this rose will hereafter be called 

 Double White Killarney, Renter 's Strain.

FUMIGATING WITH CYANIDE. 



Is Gas Used Too Strong? 



As to cyanide gas and the experience 

 of Mr. Merrill related in The Review 

 for December 14, are we not using it 

 too strong? Henry F. Michell Co. had 

 a formula in the fall bulb catalogue 

 which I copy: "Put a tablespoonful of 

 water in a galvanized iron pail. Add 

 to this one ounce of sulphuric acid 

 and use one ounce of cyanide of po- 

 tassium." The above charge is sufii- 

 cient "for a house 20x100 feet. Don't 

 open the greenhouse for at least twelve 

 hours." I have used the gas in only 

 one house, a small one, only 12x24 feet, 

 and a much stronger formula, and have 

 badly burned my tender plants. My 

 worst pest is the white fly. In the 

 late fall they completely denude my 

 rose bushes in the open and stay around
