HORTICULTURE. 



4.11 



Forced Circulation. This method re- 

 quires the service of a pump of some 

 kind. The water is heated and then 

 forced by the pump through the, pipes 

 in the greenhouse and back to the 

 boiler. The pump may be operated by 

 steam, electricity or gasoline. The old 

 lashioned plunge steam pump is, I be- 

 lieve, the most reliable, but pumps 

 driven by the other methods that I 

 have mentioned have proved satisfac- 

 tory. There are several advantages of 

 heating by forced circulation and I be- 

 lieve it is the method which will be 

 used in all large plants in the future. 

 In the first place, the size of the pipe 

 used for the mains and heating coils, 

 can be smaller than in a gravity sys- 

 tem. The water returns to the boiler 

 at a higher temperature and it is pos- 

 sible to heat a house more evenly. I 

 am sorry that I have not more time at 

 my disposal to go into the subject of 

 heating more fully. It is one that is 

 full of pitfalls, even to the initiated. 

 What I have said, outlines the general 

 principle. The ratio of determining 

 the number of pipes to the glass sur- 

 face, the size boiler required, the dis- 

 tribution and grading of pipes, size of 

 mains, etc.. are really up to the heat- 

 ing engineer, but if growers knew 

 more about these, they would not be 

 apt to have a heating apparatus de- 

 signed and installed which will prove 

 far from satisfactory and not what was 

 desired. 



The more one knows about every- 

 thing that is used or in use in one's 

 business, and that knowledge used 

 wisely, just so much more successful 

 will the business become. 



A few years ago, growing vegetables 

 under glass was almost unknown. 

 Now the cultivation of vegetables in 

 greenhouses is increasing rapidly and 

 as time goes on, I expect and predict 

 that the industry of growing vegeta- 

 bles in greenhouses would have 

 reached such proportions that we shall 

 be supplied with vegetables in winter, 

 as in summer, and the cost not much 

 greater than growing vegetables out 

 of doors. 



Vegetables and fruit grown under 

 glass have a finer flavor than those 

 grown out in the open. 



There is no country in the world 

 that offers the opportunities that ours 

 does, and it behooves us all to make 

 the best of these opportunities in what 

 ever line we may be engaged.

UNIQUE WHITEWASH USED IN 

 URUGUAY. 



i From Report of Consul Frederic W. 

 Goding, Montevideo. j 



When traveling through the rural 

 districts of Uruguay, one's attention is 

 attracted to the fine white color of the 

 farm buildings, even during the wet 

 season. To obtain this neat effect a 

 whitewash is used which is made with 

 the sliced leaves of the common cac- 

 tus, macerated in water for 21 hours, 

 producing a solution of creamy con- 

 sistence; to this lime is added and 

 well mixed. When applied to any sur- 

 face, be it of wood, brick, iron, or 

 other material, a beautiful pearly 

 white appearance is produced which 

 will endure through storms and frosts 

 for many years. In sections of the 

 United States where the cactus is a 

 nuisance, the plant might be utilized 

 in the manner suggested.

DETROIT SCHOOL FLOWER FES- 

 TIVALS. 

 A very interesting event was the 

 annual Flower Festival brought into 

 being by the Twentieth Century Club. 

 School children who got seeds from 

 this club last spring bring their prod- 

 uct to their respective schools, and 

 keen indeed was the competition for 

 the many prizes. Ladies of the club 

 and the following florists acted as 

 judges: M. Bloy, F. Danzer, F. Holz- 

 nagle, M. Sullivan. Twenty-five schools 

 participated. 



The most interesting display and 

 the one receiving first prize was ar- 

 tanged in the kindergarten room of 

 the Wingert school. The whole room 

 represented a back yard with a sum- 

 mer house in the far off corner in 

 which a tea party was in progress. A 

 serpentine walk bordered with red and 

 white asters led up to this, while beds 

 of other flowers in artistic color com- 

 binations were distributed over the 

 lawn. On the other side of the hall 

 boys busied themselves hilling corn 

 and girls took care of beds of zinnias' 

 and marigolds. 



Many of these exhibits showed very 

 practical lessons and some of the 

 flowers and their style of arrange- 

 ments, as also some vegetables, would 

 have been a credit to a professional 

 FRANK DANZER. 



Reports have come that Salzer Bros.' 

 greenhouses at La Crosse, Wis., 

 totally wrecked by a recent storm 

 which was so severe that north win- 

 dows were broken all over the city. 



Lowell, Mass.— All the florists in 



city have been notified of an ac- 



taken by the police board rela- 



tive to Sunday business. Many of the 



ts, it seems, have somewhat 



tched the rule that allowed them 



to keep their shops open until Sunday 



| so that hereafter no such thing 



will be allowed. They mav i eceive 



re up till late Saturday night, and 



make up and deliver these until 11 a 



m. Sunday, but the shops must not 



be open at all on Sunday, except to 



ul! the orders.
