The new tariff bill now before Congress 

 imposes a duty of thirty per centum ad 

 valorem on plants, trees, shrubs, vines, 

 bulbs and roots. Flowerandgrassseeds, 

 are on the free list. 



At a recent meeting of Horticultural 

 Societies in Washington steps were taken 

 to secure from Congress legislation look- 

 ing to the careful inspection of all plants, 

 trees, shrubs, etc., imported from other 

 countries, and the destruction of any 

 affected by insect or fungous pests. 



Henry McCrowe, superintendent of 

 parks at Paterson, N. J , died March 14, 

 aged 50 years. He assumed charge ot 

 the Paterson parks March 1, 1894-, and 

 his management was characterized by 

 such ability that the beauty of the parks 

 was much enhanced. 



The tenth annual meeting ot the Flor- 

 ida State Horticultural Society will be 

 held at Orlando May 4 to 7. Full details 

 may be had bv addressing the president, 

 Mr. G. L. Taber, Glen St. Mary, Fla. 

 The printed report of the proceedings ot 

 the society for 1896, of which a copy has 

 been sent us, contains many useful essays 

 and discussions, is well printed, and 

 shows that the Florida society is doing 

 good work. 



The International Horticultural Expo- 

 sition at Hamburg, to be held from May 

 1 to October 1 of the present year, was 

 officially indorsed by the Executive Com- 

 mittee of the Society of American Florists 

 at its recent meeting. The committee 

 urges American horticulturists to be ade- 

 quately represented at this exposition. 



The American Dahlia Society held its 

 annual spring meeting in Philadelphia. 

 March 17. The treasurer's report showed 

 the society to be in good financial condi- 

 tion. The annual fall exhibition will be 

 held in Philadelphia September 21 and 22. 

 Officers for the ensuing year were elected 

 as follows: Robert Craig, president; H. 

 F. Michell, vice-president; Frank C. Bru- 

 ton, treasurer; E. Clifton Taylor, secre- 

 tary. Secretary Taylor's address is 4827 

 Main street, Germantowu, Philadelphia, 

 Pa. 



The Executive Committee of the Society 

 of American Florists met at Pro vidence, R. 

 I., March 9 and 10, to arrange a pro- 

 gramme for and attend to other business 

 connected with the next annual conven- 

 tion of the society, to be held in Provi- 

 dence next August. Amongst other busi- 

 ness a committee was appointed to act in 

 harmony with the various Hatch Experi- 

 ment Stations and to devise a compre- 

 hensive plan for special investigation of 

 questions regarding plant growth, fer- 

 tilizers, etc. 



Nitrate of Soda has been recom- 

 mended for killing the destructive eel- 

 worms that affect the roots of roses and 

 other plants and which produce what is 

 commonly known as "club root," but 

 Mr. J. N. May, an expert grower, says 

 that if applied of sufficient strength to 

 kill the eel-worm it will also kill the 

 plants. In his experiments a solution of 

 one ounce of nitrate to four gallons of 

 water (only one-fourth the strength 

 recommended) killed three affected plants 

 of chrysanthemums but did not kill the 

 eel-worms in their roots. 



Double glazing for greenhouses, mean- 

 ing two layers of glass one above the 

 other with an air space of an inch or less 

 between them, comes to the surface as a 

 new idea with more or less frequency. 

 Such a double glass roof undoubtedly 

 saves some fuel in cold weather but what 

 is gained in warmth is lost several times 

 over by reduced light. Dirt is bound to 

 accumulate between the two layers of 

 glass, no matter how perfect the glazing. 

 Houses so constructed have invariably 

 been changed to a single layer after a few 

 year's experience. And the saving of fuel 

 is not near so great as might be imagined. 

 During very cold weather the moisture 

 on the roof freezes so as to close every 

 crack and make the roof practically air 

 tight. Also the double glass roof does 

 not admit the rays of the sun nearly as 

 well as the single layer of glass. 



The advance premium list for the 1897 

 chrysanthemum show of the Horticul- 

 tural Society of Chicago has been issued. 

 A new feature is an "International Com- 

 petition" in which prizes of $5 each are 

 offered for the best twelve chrysanthe- 

 mum blooms in twelve varieties, from 

 each state, territory and Canadian prov- 

 ince. The winning exhibit from each 

 state is to afterward compete for a prize 

 of $50, to be awarded to the best of these 

 prize state exhibits. There are the usual 

 liberal premiums for chrysanthemum 

 plants and flowers, roses, carnations, 

 decorative plants and floral arrange- 

 ments. Two classes that are open to 

 amateurs only are "Best five plants in 



bloom" and "Best display of cut flowers." 

 Prizes of $10 for first and $7 for second, 

 are offered in each class. Copies of the 

 list may be had by addressing the assist- 

 ant secretary, Mr. W. N. Rudd, room 

 202, 185 Dearborn street, Chicago. 



The Greenhouse. 



f\ SMALL GREENHOUSE. 



A subscriber in St. Louis who received 

 some suggestions through Gardening 

 on building a greenhouse thanks the un- 

 dersigned for his ideas and will build the 

 house from 20 to 30 feet in length and 19 

 feet wide. He is still open for opinions 

 on size of glass, etc. 



The glass if laid in putty and lapped, 

 which is best if near a city on account of 

 smoke, had better not be less than 12 

 inches in width; 12xl6orl4xl6 is agood 

 size. But if you want a still lighter 

 house use 16x20 inch. Glass is more 

 expensive as it increases in size, and see 

 that there is one-fifth of white lead used 

 in the putty; that will prevent it from 

 rotting. If you can afford to have side 

 glass it will make your house very much 

 more valuable for growing plants; that 

 is if your walls are 4 ft. 6 inches high let 

 2 ft. of it be of glass and it will cost little 

 more to have this side glass in sash, 

 hinged so that they can be used for venti- 

 lation in summertime, as we never can 

 have too much ventilation during the hot 

 summer months. 



One ot the most important things in 

 building a greenhouse is to have an iron 

 column directly under the ridge pole; it 

 can rest on r. flat stone. One and a quar- 

 ter inch is large enough for the column 

 which can be common pipe. If your ridge 

 is well supported the house cannot spread. 

 In conclusion go to a practical commer- 

 cial florist in your neighborhood, who 

 will know more about building than any 

 of the ordinary builders. Wm. Scott. 



STREPTOCARPUS WENDLANDII. 



We raised a number of this new strep- 

 tocarpus in February of last year. They 

 have grown very well, as the leaves are 

 now about two feet long by ten inches 

 wide. As this plant makes only one leaf, 

 we put three plants to a pot, pointing 

 them out in different directions. In this 

 way thev have a better appearance than 

 if only one plant was used. The leaves 

 hang gracefully over the sides of the pots, 

 curving inwards, and as a plant it is 

 ornamental without any flowers. It is 

 said to have nice spikes of bluish flowers, 

 but of them we cannot speak as our 

 plants have not flowered, and it is this 

 part that is now troubling us. Some of 

 our plants have been showing flower for 

 over three months, the spike being about 

 an inch long all that time, but they don't 

 move a bit. and this being a new plant 

 we are anxious to see it in flower. Have 

 any readers of Gardening had any expe- 

 rience with this plant? David Fraser. 



SWAINSONA GALEGIFOLIA ALBA. 



F. N. B. expresses great interest in an 

 article on the above plant which appeared 

 in Gardening of March 1, but says 

 that with her it has been a very 'dis- 

 appointing plant." It flowered very 

 sparingly at first, which was attributed 

 to extreme growth. Then it was planted 

 out last spring but no blossoms appeared 

 during the summer. In September it was 

 lifted and put into a 7-inch pot, and up
