Test No. 8.

Test Made at Aberdeen, Scotland.

TEST ON TWO WOOLLEN MILLS.

The mills are usually driven by a water wheel and two engines. For convenience during the tests the water wheel was stopped. The smaller engine is called No. 1 and the larger engine No. 2. No. 2 Engine was coupled up to take the load usually driven by the water wheel.

No. 1 Engine - Hicks, Hargreaves, Ltd., Bolton.
