ents also affect the distribution of 

 species. 



The chemical and biological prop- 

 erties of the soil constitute more im- 

 portant factors in plant growth than 

 mechanical properties; but this phase 

 of the subject is so extremely com- 

 plex, notwithstanding the immense 

 amount of research given to it. that 

 the subject is very far from being ex- 

 hausted. 



All greenhouse soils contain more 

 or less large quantities of plant food, 

 and in all soils various subsidiary 

 constituents and admixtures which 

 plants can use. are found. It is pos- 

 sible, therefore, to grow good crops in 

 most soils for years without the use of 

 fertilizers or manures providing they 

 have constant tillage. 



The micro-organisms of the soil also 

 play a most important role. In gen- 

 eral, the richer the soil, the larger the 

 number of micro-organisms found. 

 Tillage stimulates bacterial activity, 

 and the various modifications which 

 these innumerable small soil organ- 

 isms bring about in the soil are very 

 complex and understood only in a gen- 

 eral way. It is known that they de- 

 compose various substances in the 

 soil; that some of them accomplish 

 nitrogen fixation, some de-nitrification 

 and others are nitrifying organisms. 

 Besides the presence of a large bac- 

 terial flora in soils — the number of 

 bacteria sometimes exceeding millions 

 to the cubic centimeter-— numerous 

 forms of fungi may be found, besides 

 algae and various types of active ani- 

 mal life. In a medium containing 

 such a vast number of different types 

 of organisms much antagonism and a 

 ■severe stniggle for existence necessar- 

 ily exist. It is also known that many 

 chemical substances such as formalin, 

 carbon bisulfid, etc.. affect the or- 

 ganisms in the soil and also act 

 as a general stimulus to plants. Vola- 

 tile- chemical substances have a direct 

 ■stimulative effect on the crops and in 

 some cases probably improve soil con- 

 ditions by destroying antagonistic 

 species. In the same way soil steri- 

 lization produces exceptionally fine 

 crops. Soils, however, differ so great- 

 ly in different localities that while 

 some are gi'eatly benefited by steam- 

 ing, others are affected unfavorably 

 by this process. It is known that the 

 process of steaming soils to 212° P. 

 greatly modifies their chemical com- 

 position, and in some cases produces 

 toxic substances which act injuriously 



to the crop. Russell and Darbishire 

 found that crops obtain three times 

 as much nitrogen and twice as much 

 phosphoric acid and potash from 

 steamed as from unsteamed soil. 

 Steaming has a similar effect to aera- 

 tion from the fact that an exchange 

 of gases takes place.

WHAT CONVENTIONS DO. 



In a little talk before the Lancaster 

 (Pa.) Florists' Club, A. M. Herr said 

 some nice things about the Boston 

 Convention and the Boston florists. 

 He expressed especial appreciation of 

 the glad hand that was extended to 

 the visitors as they stepped from the 

 gang plank of the steamer and thus 

 corroborated the many testimonials to 

 the efficiency of the committees en- 

 trusted with this work. In the Con- 

 vention Garden he was particularly 

 impressed with the two new gerani- 

 ums My Maryland and Scarlet Bedder 

 and the exhibition by the Massachu- 

 setts Horticultural Society in Horti- 

 cultural Hall was a revelation. In 

 chiding his fellow members tor hav- 

 ing neglected the opportunity to see 

 these evidences of advanced horticul- 

 ture he said that in taking advantage 

 of these things "you get your sub-con- 

 scious mind filled with ideas that come 

 out during the year into your work- 

 ing brain, and you get that accumula- 

 tion of bile off your liver that has 

 gathered there the preceding year 

 through disappointments and too close 

 application to work."
