Sutherland Reclamation, 
was obtained by conducting it from the hills In surface furrows 
to the spot where the engine was at work. Wherever this plan 
could not be adopted, it was necessary to cart it up from the 
main streams. The chief stream at Achintoul runs deep down 
between high banks, and great difficulty was at first experienced 
in getting up these banks, from the horse getting slung up by 
the cart tipping backwards. To meet this difficulty Mr. Greig 
has invented the Sutherland Water-cart (Figs. 12 and lo). 
Fig. 12. — End view of the Sutherland Water-cart. 
If a water-cart of the ordinary form, with its barrel placed 
longitudinally, is only half filled, in order to adapt its weight 
to the power of the horse, the result will be that in ascending 
a steep incline the water falls to the back end of the cart, and 
tends to lift the horse from the ground. Even if it is full, there 
is sufficient tendency in this direction to lessen the tractive 
force when the horse is on a gradient. In the new cart two 
barrels, AA, are placed across the frame, one before and one 
behind the axle of the carrying wheels. These two barrels are 
coupled by a pipe connected to the bottoms, having a cock, B, 
in the centre. A pump, C, with a hose, is fitted on to the first 
barrel, for the purpose of drawing the water from tlie stream. 
It will be seen by this arrangement that it is in the power of the 
carter to load his first barrel full, with his last barrel half
