This roller is similar to the one exhibited hy 

 Mr. Fisher (No. 2\ having sheep-foot pro- 

 jections on the outside of the cylinders, with 

 a contrivance to lubricate the inside of the 

 spindle without removing the cylinders. 



Before concluding our Eeport on the field implements that came under our 

 notice, it may be well to put the question, how far the principle of self-clean- 

 ing increases the draught, and which kind of self-cleaning princij)le increases 

 it the least.? The dynamometer might throw some light on this question.

Amongst the Lliscellaneous Class this year, the brick and drain tile ma- 

 chines were appointed for trial. In reporting upon them we can say but little 

 except recording the results brought out by the dynamometer, and coui]iaring 

 them witli those of previous years. Indeed every year must be pregnant with 

 riioi'e than ordinary efforts of genius to bring even novelty to bear upon so 

 simple a process as tile-making. While admitting the strength, durability, 

 atid first-rate workmanshiji of the machines which come more particularly 

 under our notice, we respectfully venture to express the feeling generally preva- 

 lent amongst the purchasers of prize implements, that, whatever may be said 

 of the over plethority of animals exhibited for the Society's prizes, they do not 

 excel the normal excellence prescribed by its rules so much as implements 

 frequently supplied fall short of the standard of those stamped with the So- 

 ciety's aiiin'obation. 



The pipe and tile machines selected for trial were Scraggs', Clayton's, and 

 Whitehead's. It will be seen that Scraggs' machine consumed less power 

 in screening the clay, but AVlntehead's more than compensates for it in making, 

 the tiles, so that we considered the latter entitled to our first consideration — 

 whilst the near approach of Mr. Scraggs to every requisite excellence entitles 

 liim also to the Society's ajiproliation. AVe have awarded 5/. to Mr. White- 

 head, Al. to ^Ir. Scraggs, and commend Mr. Clayton's machine, considering it 

 superior to horizontal machines for making tiles of large diameter. 



Subjoined are the tabular results, in which will be seen a gradual improve- 

 ment during tlie last three years — the number of imperfect pipes was so trivial 

 as not to be worth recording : —
