156 BOARD OF AGRICULTURE. [Pub. Doc. 



ical in continuing several important experiments already 

 alluded to. These experiments include the alternation of 

 leguminous and non-leguminous crops with and without 

 nitrogen, the effect and economy of different forms of phos- 

 phoric acid, the effect of various forms and combinations of 

 plant food upon the production of garden crops, and the 

 value of a rotation of manures upon the yield of permanent 

 grass lands. 



Horticulture. 



The work in horticulture will be continued on much the 

 same lines as heretofore. It is planned, however, to test 

 the many new varieties of vegetables so extensively adver- 

 tised and highly recommended by seedsmen. It is hoped 

 at no distant date to establish a seed control in connection 

 with this department. Laboratories for this purpose are 

 quite common in Europe at present. Such a step could not 

 fail in improving much of the seed now offered for sale. 



Botany. 



In the department of botany several lines of work will 

 be undertaken. A study of some of the diseases affecting 

 farm and garden crops will be made. Tomato scab will be 

 given careful attention. Various fungicides will be tested, 

 especially those likely to prove valuable in greenhouse 

 work. Applications of different solutions will be made to 

 distinct numbers of plants, and the effect carefully noted for 

 a considerable length of time. In the laboratory fungi- 

 cides of different strengths will be inoculated with fungous 

 germs, to see if the dilute solutions will admit of any fun- 

 gous growth. 



Greenhouse conditions will be carefully observed, to see 

 what temperature, degree of moisture, barometric pres- 

 sure, etc., favor the growth of different fungi. Such 

 knowledge is absolutely essential in order to teach one the 

 best methods of preventing the growth of these organisms. 



Cucumbers will be grown in soil inoculated with nema- 

 todes ; different methods of soil treatment will be tried, to 

 see if practical means can be found to eradicate them.
