It will thus be seen that an experience of ten years was suffi- 
ent to demonstrate the utility of the Trials of Implements, 
he anxiety of manufacturers to obtain the Society's medals 
id prizes kept pace with the increasing importance which was 
tached to them by the agricultural community. It therefore 
■came necessary to spread over a series of years the labour and 
ist of submitting to trial the ever increasing variety of farm 
iplements. Accordingly a triennial scheme was arranged in Classification 
?55, as the result of an interview between the Council of the °^ implements 
)ciety and a deputation of the Agricultural Implement manu- 
cturers. This first division was as follows : — 
1. Implements for tillage and drainage. 
2. Machines for the cultivation and harvesting of crops. 
3. Machines for preparing crops for market and food for 
cattle. 
This scheme was expanded to a quadrennial one in 1859, but 
ain reduced to a triennial in 1864, and afterwards enlarged 
a quinquennial in 1869. This last classification, in spite 
its extension, was found too condensed for practical use, and 
is further expanded on account of the time required to try, 
aroughly and scientifically, the increasing number of imple- 
?nts in each class. The following statement of the amended 
ossification, arranged in its natural order and not as actually 
ed, will give the best idea of the trial-system in its final 
1 velopment : — 
1. Horse-power machines and implements used in tillage. 
2. Steam-power machinery used in tillage. 
3. Machines and implements used in the cultivation and 
carrying of crops. 
4. Machines and implements used in the harvesting of 
i grass crops. 
5. Machines and implements used in the harvesting of 
grain and root crops. 
6. Machines and implements used in the preparation of 
crops for market. 
7. Machines and implements used in the preparation of 
food and in the feeding of stock. 
At the present time a rotation or classification of implements Existinsr 
1 trial in successive years is not included in the Society's pro- system, 
fimme. For some years the cost of the trials of agricultural 
iplements to the Society alone has exceeded an average of
