poultry. The veterlnaiy science laboratory will likewise include both 

 methods of instruction and of research, and will contain illustrations 

 of typical results of the stations' work in study of animal diseases and 

 their control. 



Dairying will constitute a prominent feature in point of space and 

 in variety and character of methods and results presented. There will 

 be a working- dairy laboratory, together with a model creamery for 

 purposes of instruction. The results of the stations' work in showing 

 the relation of food to (puility of dairy products, the effect of micro- 

 organisms, the curing- of cheese, and other work relating- to the prog- 

 ress of dairying, will bo illustrated ])y specimens, models, and charts. 

 The important work which has biu'u done in sugar production, both 

 from sugar cane and from the sugar beet, as well as the studies on 

 maple sugar, will l)e shown in a sugar laborator}^, adjacent to Avhich 

 other lines of agricultural mamifactures will be illustrated. 



The exhibit in rural engineering will include the layout of farms, 

 farm buildings and machinery, irrigation, drainage, and road construc- 

 tion. In connection with the irrigation and drainage exhibits experi- 

 mental and model systems will ])e shown, with fields arranged to 

 illustrate different methods of irrigation, drains for removing excess 

 of water, and provided with a pumping plant. This should prove one 

 of the most attractive and instructive features of the whole exhi})it, but 

 from its character need not l)e ver}' expensive. 



One controlling idea which has been borne in mind in planning the 

 exhibit has been to provide as many features as })ossil)le which would 

 in a measure be self-explanatory^ and would attract the attention of the 

 passer-by. The experience of the past has shown tliiit ol)j(»cts, models, 

 and exhibits containing some feature in ojx'ration ar(^ a more success- 

 ful means of illustration than charts and diagrams, although it is dif- 

 ficult to fully illustrate some lines of station work without tln^ latter. 

 Frequenth^ some feature can be used to attract the attention, which 

 can then be led to a more detailed presentation. Several attendants to 

 act as demonstrators are planned for. 



In addition to the exhibit in the Palace of Education, tln^ exposition 

 authorities have agreed to provid(? a l)uilding where the work in animal 

 husbandry, especially in stock judging, can be shown. This will con- 

 sist of a stock-judging room where the work can actually be carried on 

 with provision for block tests, the cutting up of beef, cooking tests, 

 etc. A considerable sum of money has been set apart by the committee 

 for the purposes of this exhi])it outside the education building. 



The plans for the preparation of the exhil)it include the collabora- 

 tion of the Office with the central office of the committee. In the case 

 of certain laboratories and parts of the exhibit the assembling of the 

 materials, and in general the method of presentation, will be assigned
