tection from the midwinter sun by a 

 covering of straw. They are twice as 

 large as pompoms and coming, as they 

 do, a month sooner, they give much 

 more satisfaction and as a commercial 

 proposition are well worthy of serious 

 consideration. 



It is peculiar to note that the two 

 American varieties, Smith's Advance 

 and Golden Glow, grown outside and 

 handled the same way, have given us 

 no results whatever. All the earliest 

 llowers have either turned black or 

 failed to develop. The two latter varie- 

 ties under glass, disbudded, we have 

 been cutting for the last two weeks, so 

 it is entirely a matter of their being 

 unable to withstand the outdoor con- 

 ditions. Chas. H. Totty. 



TEOUBIE WITH POT MUMS. 



I am sending herewith some leaves 

 from chrysanthemum pot plants with 

 which I am having trouble. Note the 

 dotted points on the leaves. The black 

 spots have a little caterpillar inside. 

 Please tell me what to do, for I already 

 have these troubles on my pot mums 

 and it is spreading to the poinsettias.

The raised dots on the leaf are some 

 form of fungoid disease, although I 

 am unable to say what. The microscope 

 fails to reveal any sign of life and I 

 am of the opinion they will do little 

 harm to the development of the flowers, 

 particularly if the leaves are sprayed 

 with a solution of sulphide of potas- 

 sium, as frequently recommended in 

 these columns. 



The black spots noted with the cater- 

 pillar on the inside of the leaf are the 

 Tephritis onopordinis. The egg of this 

 insect is deposited in the leaf and the 

 larvae eat the tissue, leaving only the 

 front and back skin of the leaf to pro- 

 tect them. To spray in any manner is 

 useless as the skin of the plant pro- 

 tects the larvae and insecticides never 

 reach the place where they could do 

 good. I would recommend hand-pick- 

 ing, or jnst squeezing the leaf with the 

 fingers where the insect is lodged.

 entry fee of $2 should be forwarded to 

 the secretary not later than Tuesday of 

 the week they are to be examined, or it 

 may accompany the blooms. Seedlings 

 and sports are both eligible to be shown 

 before these committees, provided the 

 raiser has given them two trials to 

 determine their character. Special at-

A D0X7BLE CANNA. 



A new type of canna has originated 

 on the farm of the Conard & Jones Co., 

 West Grove,. Pa, It bloomed in the 

 patch devoted to seedlings by Antoine 

 Wintzer, vice-president of the company, 

 the greatest canna hybridizer it has 

 ever been my pleasure to meet. The new 

 canna bears flowers formed by eight 

 petals, just double the usual number. 

 The double variety originated from a 

 seedling of the old Alba rosea variety 

 in the third generation as pollen parent, 

 and Buttercup, the standard yellow 

 canna of today, as seed parent. The 

 new seedling is of medium height, with 

 robust growth, green foliage and clear 

 orange-yellow flowers. The double form 

 gives the flowers a distinct character 

 that is most pleasing. Should this type 

 become fixed it will open a vast field of 

 possibility to the canna hybridizers of 

 tomorrow, possibilities that make cer- 

 tain the development of the canna at 

 an even grejiter pace than the wonder- 

 ful development of the last decade. 



I spent a delightful afternoon witb 

 Mr. Wintzer last week, going over his 

 cani^s. They were marvels of beauty 

 that' warm September day, a sight so 

 orlorious that the time seems close at 

 hand when the canna must stand first 

 among outdoor decorative plants. The 



standard varieties, introductions of the 

 last few seasons, and the leading novel- 

 ties were planted in long rows side by 

 side, giving an excellent opportunity 

 for comparison. 



The seedlings were in a large patch 

 by themselves. Fully two-thirds of 

 them were of such promise that they 

 would have merited further trial ten 

 years ago. One long row of seedlings 

 from Blanche Wintzer, the coming 

 white, were all wonderfully fine — strong, 

 even growth, with magnificent flower 

 spikes bearing large flowers, mostly 

 pleasing shades of pink, with some lemon 

 yellows and some whites. An interest- 

 ing attempt is being made to increase 

 the vigor of the new varieties by infus- 

 ing the wild Costa Rica blood. The 

 Costa Ricans now in their second gener- 

 ation show decided improvement over 

 the original stock. Some quite fair 

 flowers were seen. These were pinks 

 and clear yellows. They do not show 

 any more vigor than the home-grown 

 stock and cannot compare with it in any 

 of the desirable qualities. 



The wealth of material makes it pos- 

 sible for Mr. Wintzer to give scope to 

 his store of knowledge in cross fertiliz- 

 ing. Beyond the division of tall and 

 dwarf, bronze foliage and green, erect 

 and drooping, free-blooming and shy, 

 red flowers and yellow, pink and white 

 with their many variations, comes this 

 cross between the canna with ideal fo- 

 liage and the canna with perfectly 

 formed flowers, to say nothing of the 

 early bloomer, the self-cleaner and other 

 desirable qualities. 



The effect of feeding on cannas was 

 manifest. The portions of the fields
