 "We send to you by tbis inail a specimen 

 c/canna seedling. The clearness of its 

 color is unique with us." 



The petals are of a clear go den yellow 

 without any spot whatever but the sta- 

 mens filament and style are deeply tinged 

 wfth red. As a flower the petals are far 

 too narrow to render it of any value, and 

 's regards its clear yellow color there are 

 othefcannas just as clear and that show 

 no red whatever in the stamens, filament 

 or throat. Two of these are now in 

 bloom at Dosoris. But no pure yellow 

 canna that we have yet seen is good 

 enou-h to name and perpetuate except to 

 breed^from hoping for improvement, the 

 petals are too narrow.

FILLING IN ABOUT T«E TRUNKS OF OLD 

 TREES. 



R W P., Highland Park, 111., asks some 

 quekionsin regard to filling in around 

 trees, and I state the following as my ex- 

 perience in that matter: 



In the fall of 1888 by filling m around 

 our office building quite a number ot trees, 

 consisting of elm and ash, were boxed up 

 and the boxes filled with rubble stone. 

 Some of the trees were about 4 teet in 

 circumference and they were covered up 

 to about 31/2 feet deep. To-day they stand 

 as healthv looking as any in the park, 

 notwithstanding that dirt has gathered 

 over the stones, covering them with a 

 green turf. Among the trees were also 

 same cottonwood, but these w-ere not 

 boxed. Two vears afterwards by building 

 approaches to a new bridge a majestic 

 specimen of a cottonwood measuring b 

 feet and 9 inches in circumference, bad 

 either to be cut down or stand a /'""g 

 in of between 7 and 8 feet. I .decided to 

 fill it in without boxing. This filling m 

 was done in the spring, and when the 

 other cottonwoods stood m their green 

 clothes this specimen did not show any 

 signs of life. I waited patiently, having 

 the best of hopes that it would come out 

 all right, and after about two weeks ot 

 waiting it started to produce a fohage 

 tar superior to any of its kin in the park, 

 and to-dav it is by far the most healthy 

 looking of the lot. J.\s. Jenson.

Filling in about a big sycamore or 

 button-ball tree (P/atanus occidentalis). 

 —Mr. Geo. H. Brown, superintendent ot 

 public parks and grounds in Washington, 

 D C, when at Dosoris the other day told 

 us about a big svcamore tree that stood 

 in his way in grading for a street, the 

 land had to be filled in six or seven feet, 

 and as he disliked to destroy the tree he 

 filled in around it as he would around a 

 post without boxing or rubble either and 

 headed back the branches considerably. 

 The tree didn't seem to be any the worse 

 for its trunk being buried, on the con- 

 trary, it very soon started to root from 

 the encased stem into the new soil, and it 

 stands to-day one of the healthiest trees 

 in the Capital grounds. But he remarked 

 all trees won't do that, only a few kinds 

 will root from the buried stems. 



obliged to fill in owing to railroad im- 

 provements some eight years ago. All of 

 the trees were planted about 18 to 20 

 vears ago, and they are now vigorous 

 and in good health; the filling is a loarav 

 subsoil and rocks. Here is the depth of 

 filling, no precautions were taken, 

 branches and all were covered in: 



One purple beech 9 feet, one Picea Picbta 

 9 feet, one common maple 5 feet, two 

 arbor vit<-E 5 feet, one Magnolia Soul- 

 angeana 6 feet, one weeping beech 5 feet, 

 one sycamore maple 5 feet, one Bartlett 

 pear 5 feet, one apple tree 3 feet, one Nor- 

 way spruce 3 feet, one Austrian pine 5 

 feet, three pear trees 4 to 5 feet, cherry 

 and apple trees on a slope from4to "feet.

FINE TREES FOR WINDBREAK. 



I followed vour advice in regard to a 

 windbreak, last spring and set 50 Aus- 

 trian and 50 Scotch pines. The trees were 

 shipped from Wisconsin, were over three 

 weeks on the road during the terrible hot 

 week we had and about 70% are doing 

 finelv, almost to my surprise although 

 thej' have had the fiest of care. Nearly 

 every one that died was the Scotch.

 this summer. What a beautiful pink rose 

 this is! 



But rose Mrs. Uegraw, pink and a 

 Bourbon, is the fullest, cleanest and best

FILLING IN ABOUT TREES. 



W K P makes inquiries in Gardeninu, 

 of Iu1v1.'-> about filling in about trees 

 etc" Pcrhajis it might be of some benefit 

 to iiini and others if I state what wcwere 



Actinidia roLYGAMA.— I lately saw this 

 vine on a neighbor's porch in a position 

 so exposed to the winter's severity that 

 the trumpet vine (Tecoma radicans) 

 freezes to the ground. It had reached a 

 height of some thirty feet and was grow- 

 ing luxuriantly. My specimen is planted 

 in the shade, at the root ot a tree and in 

 a rather dry situation and makes no 

 headway. It shall have new quarters.

Roses. 



BLACK SFOT ON ROSES. 



E. C, Decorah, Iowa, asks: "What is 

 the matter with my roses? These black 

 spots (leaves enclosed) make their appear- 

 ance, then all the leaves fall, but with 

 good nursing they bud out again; the 

 only thing that seems to help is a weak 

 solution of sulphate of copper." 



The trouble is Black Spot, a fungus dis- 

 ease widespread among both indoor and 

 outdoor roses. Technically it is known 

 as Actinonema Rosee. The spores being 

 wafted in the atmosphere are apt to at- 

 tack roses anywhere and at any time dur- 

 ing the growing season, but uncongenial 

 conditions of cultivation and conse- 

 quently an unhealthy state of the plants 

 invite the disease. Quite healthy plants 

 too are attacked. A wet season, sudden 

 changes of weather, and undue soaking 

 of the ground, fog, too heavy a mulching, 

 too much animal manure in the soil and 

 the like aggravate the disease. Accord- 

 ing to Dr. Byron D.Halsted "This trouble 

 may be held in check by the carbonate of 

 copper compound, using three ounces of 

 the carbonate of copper, one quart of am- 

 monia and 50 gallons of water. The 

 spraying should be done once a week, us- 

 ing a hose and a nozzle that gives a fine 

 spray. The point should be to wet every 

 part of the plant and yet not drench it. If 

 many leaves have fallen from the plant 

 they should be gathered up and burned." 



Mrs. John Laing rose is in bloom again 

 and among the H. P.s the fullest of all. 

 nnfortutiately, however, it is pretty badly 



Aquatics. 



A POND FOR Aquatics — 

 K. M. W., Ontario, we would say: Have 

 the pond out in the open sunshine. Bet- 

 ter let it alone till spring, as beyond 

 making the basin and walling it you 

 couldn't do anything more this fall, for it 

 is too late now to plant out water lilies. 

 You can raise a good many varieties from 

 seed, especially Nywphwa zanzibarensis, 

 sown in pots of soil plunged just over the 

 brim in pans or tubs ot water in the 

 greenhouse in winter, but as regards AT. 

 odorata in all its forms, Marliacea in its 

 forms and other choice but inexpensive 

 sorts we believe you will get more satis- 

 faction and quicker results if you buy a 

 plant of each to begin with. You can get 

 your soil ready now though. Make up a 

 pile of the best sod loam and cow manure 

 as you would for roses, and turn it over 

 before winter sets in to mix it well 

 together. Don't use horse manure. 

 Water lilies love very rich soil. And have 

 a heap of clean tharp sand at hand to 

 spread over the top of the soil when you 

 plant theHlies, to prevent the water being 

 muddy, as jou have both a cellar and a 

 conservatory, y u could even begin get- 

 ting plants together now. Get a few 

 empty butter tubs with iron hoops, at the 

 grocer's, saw them down to the hoop, 

 and scrub and scald them thoroughly. 

 Now if you can get -odorata lilies from the 

 ponds anywhere, or a spare plant of any 

 of the cultivated hardy sorts, or nelum- 

 l)iums from your friends you can plant 

 them at once into these tubs using light 

 sandy soil, or sand alone forthat matter, 

 and keep them in a cool cellar— where 

 potatoes or apples are kept would be a 

 good place — over winter. Empty oft' the 

 water, but keep the soil wet. If they live 

 til spring plant them out in the pond. The 

 tender lilies make tubers, and instead of 

 wintering big tubs filled with lilies we 

 simplv grub up a few tubers, put these 

 into pots, which we keep over winter 

 plunged in a tub or tank of water on the 

 greenhouse bench. We have an article in 

 hand on how to make a water lily pond, 

 and shall print it soon. 



The Greenhouse. 



GREENWOUSB QUESTIONS. 



by v. \v.. bicintvre. iowa. 



1. Heating a small greenhouse.— 

 "1 found my old cook stove, bricked over 

 with flue laid along the ground very good 

 last winter for heating my 9x12 foot 

 greenhouse, but it smoked." 



Ans. Bother the old stove, and its 

 parching breath, pungent smoke and per- 

 nicious gas. Send to the boiler men ad- 

 vertising in Gardening, tell them exactly 

 what you want and ask them what they 

 can do for you. The expense isn't much 

 and the result is perfect satisfaction. 



2. "Wh.\t can I GROW on the ground 

 under the south bench, the flue is on the 

 north side:"'
