lamp is equal to that of three ordinary carriage-lamps. The 
rays from a pair can be cast in any direction, and spread to 
such an extent as to meet a few yards ahead. The reflectors 
being slightly curved, the light takes a downward direction, 
illuminating the ground in front of the carriage for nearly 
fifty yards. For dog-carts, one dash-board lamp with reflectors 
gives ample light. These lamps are manufactured by Insole 
and Grimley, of 76, Hurst Street, Birmingham, and cost IZ. 125.

The subject of Compound Engines, as applied to agricultural, 
portable, and traction powers, is receiving increased attention. 
It will be remembered that Messrs. Fowler and Co., at Kilburn, 
showed a Fixed Engine for Agricultural purposes fitted with 
compound cylinders. This was followed up at Carlisle by 
Messrs. Garrett and Sons, who applied their apparatus both to 
portable and fixed engines. Besides these, at Derby there 
were shown Compound Traction Engines by Messrs. Aveling 
and Porter, and by Messrs. Burrell and Sons. It is therefore 
evident that this important economical improvement is occupy- 
ing the serious attention of exhibitors, and it is probable that 
their inventive faculties might be stimulated by the offer on the 
part of the Society of substantial rewards for success. I am very 
glad to be able to append to this report a valuable communica- 
tion from such critics as Messrs. Easton and Anderson (p. 661), 
the Society's Engineers, which very clearly brings the subject 
up to date, and shows what are its future possibilities. I cannot 
close this short and very meagre report, without expressing our 
cordial appreciation of the unvarying consideration shown the 
Judges by the Stewards of Implements, to facilitate in every 
possible way our work ; and it would be equally an omission 
if I failed to express my own personal obligations to the 
Engineers, and especially to Mr. F. S. Courtney, for the valuable 
help he was ever ready to afford, and which, as regards points 
of construction, was most valuable. 
XXXIV. — Report on the " Working Dairy " at the Derly Show. 
By Herbert J. Little, of Coldham Hall, Wisbech. 
Milk and honey were to be among the special blessings of the 
" Promised Land." It is evident from an ancient Book how 
much importance in Eastern imagination was attached to an 
abundance of these essentials of human and animal existence. 
With the advance of civilisation, honey has had to yield in im- 
portance to other forms of saccharum extracted from the vegetable 
world by human instead of insect industry, but none the less has
