844 IOWA DEPARTMENT OF AGRICULTURE 



The machinery show was, as usual, very large and very instructive. 

 The various lines of farm machinery were well represented and some 

 new things were to he seen. What is termed a "pollenizer" for clover 

 is a new invention. It is a large brush that is hauled over a clover 

 field when nearly in full bloom in such a manner that the bristles of the 

 brush are supposed to open the clover flowers and pollenize them. It is 

 said that if a field of clover is gone over twice with this pollenizer that 

 the harvest of double the amount of seed ordinarily received is a prac- 

 tical certainty. Whether the machine will do what the inventors claim 

 for it we are unable to say. The display of cement machinery and of 

 the various uses to which cement can be put was very interesting. 

 Several kinds of moulds for making cement building blocks and fence 

 posts were prominently displayed.
