Lemoinei and D. gracilis; Ligustrum 

 Ibota and L. ovalifolium and some 

 other varieties, will root within thirty- 

 days. The above-named lilacs need 

 more time. Now as to ventilation, do 

 not give any until the cuttings are root- 

 ing; then give a little and gradually 

 decrease the spraying somewhat. When 

 cuttings are calloused, a little venti- 

 lation given on a cloudy day will do 

 little harm, but the same amount given 

 on a hot, clear day would be harmful. 

 Boiled down, a few essentials needed 

 for the successful propagation of de- 

 ciduous green-wood cuttings are: Wood 

 must be in a medium ripe condition; if 

 too soft, damping off will result; care 

 must be taken to prevent wilting be- 

 fore and after insertion; cuttings must 

 be sprayed lightly, but frequently, so 

 that they will hardly ever appear dry 

 for the first few weeks; little or no 

 ventilation should be given until the 

 cuttings are rooting; when the cuttings 

 are rooted, reduce spraying materially, 

 gradually increase ventilation and 

 light, and later remove the sashes alto- 

 gether and leave them off until freez- 

 ing weather removes any foliage on 

 the cuttings. These hints are intended 

 for the many small growers who want 

 to root some deciduous shrubs. Nurs- 

 erymen and large propagators do not 

 need such advice. C. W. 



TAKING PHLOX CUTTINGS. 



Will you kindly advise me of the 

 method followed in ])ropagating peren- 

 nial phlox from cuttings — the time the 

 cuttings arc taken off, etc.? 



J. H. C— fan. 



The native varieties of Phlox panicu- 

 lata and P. maculata are propagated by 

 side shoots and by cuttings of well 

 matured shoots. Cuttings should be 

 taken from the young, vigorous shoots 

 on the outside of the clump. The spring 

 is the best time to take the cuttings. 

 Place them in sand and keep them well 

 watered. This will give you strong 

 plants in the fall, fit for selling. 



GRATTING GYPSOPHILA. 



Will you please tell me how to graft 

 Gypsophilapaniculata flore-pleno? What 

 temperature is required and how should 

 the soil or sand be prepared? What 

 time of the year is best? Is budding 

 wax or raflfia used to hold the graft in 

 place? What is the best part of the 

 root to use and how should it he pre- 

 pared? O. J. S.— Colo. 



The writer has done no grafting of 

 Gypsophila paniculata flore-pleno and 

 would like some reader who has done so 

 to give this subscriber the information 

 he desires. 



The roots must be used to take the 

 grafts. Late winter or earlv spring 

 should be the ideal time for this work. 

 Keep the grafts close and warm until 

 they "take." Use sand or verv sandv 

 soil and tie the grafts with raffia. Wheii 

 growth starts give the plants a little 

 more air and pot them off singlv. Keep 

 them rather close until thev liave he- 

 come established. " C, W. 



MEASURING STEAM. 



To secure more accurate data than 

 has heretofore been possible in regard 

 to the heat necessary for different types 

 of houses and under different methods 

 ot heating, the American Greenhouse 



Standing Shower Wreath of a Variety of Flowers. 



Mfg. Co., of Chicago, has installed in 

 the greenhouses at Pana, 111., where its 

 factories are located, meters to measure 

 the flow of steam. At the range of 

 Walter A. Amling a group of connected 

 houses will be measured. At the range 

 of A. N. Nielsen a big house, 61x400 

 feet, will be measured and a group of 

 34-foot disconnected houses will he sup- 

 ]died with a separate meter. Thus three 

 different types of constructions will be 

 studied with a view to determining the 

 relative amount of steam each tvjie re- 

 ijuires in relation to its size. 



It is planned' to equip the range of 

 Rtielow Bros., at Niles Center, 111., witli 

 a similar steam flow meter. The Stielow 

 houses are heated with oil, .-md valuable 

 figures as to the relative merits of oil 

 and coal are anticipated. 

 ^ This experiment is not a cheap one. 

 Kach meter costs about $400 to install. 

 The three at Pana and the one at Niles 

 Center are expected to be ready to 

 measure the steam used next winter. 

 Such meters are manufactured bv the 

 General Electric Co. and the Republic 

 Flow Meters Co. Hitherto their use 

 has been confined to large power plants, 

 where the extensive flow of steam war- 

 ranted the expense of installing a me- 

 ter. ]f the experiments at Pana !in<l 



Niles Center reward the American 

 Greenhouse Mfg. Co. with valuable sta- 

 tistics, doubtless the use of such meters 

 in large greenhouse establishments the 

 country over will become general. 



STANDING SHOWER WREATH. 



A wreath quite popular and much ad- 

 mired down in Columbus, O., is the stand- 

 ing "sliDwer wreath," whicli is a crea- 

 tion of the Wilson Seed & Floral Co., of 

 that city. An illustration of such a 

 wreath ai)pears on this page. The de- 

 sign liere shown was sent to the funeral 

 of a prominent local automobile dealer 

 by the Association of Ford Dealers. 



In this ease the wreath proper con- 

 sisted of blue and lavender sweet peas. 

 Sunburst roses and valley, while the 

 liase was made of yellow and bronze 

 snapdragons and Columbia roses. The 

 firm has made this design in various 

 sizes and heights, its popularity hav- 

 ing created a great demand for it. 



FLOWERS FOR SICK SOLDIERS.

 side of Chicago, an idea for the distribu-
