Rods that arc batteredand bruised by hammer blows are notonly unsightly but arc a sure indicationof unskilled and careless workmanship. A point that is well worth remem-bering is the testing of the rod whenone end is attached in order to showwhether it points exactly to the center When the front end of the rod isconnected it should also be observedwhen the strap of the other connectionis pushed over the butt end of the rodfor the purpose of driving in the boltswhether there is any twist on the rod ornot. If any obliquitv- in the alignmentof the rod and strap is visible, the brassat the end should be refitted and a per-fect adjustment and alignment securedbefore driving the bolts in their will occur to the thoughtful me-.

In testing the movement or degree ofslackness of the rods time need not bewasted testing the rods in other thanthe central positions. It is only when;it the dead centers that the connectingrods arc free from the great strain ofmoving the engine, and are necessarilypulling in one direction or the other, andshould not be expected to be moved easily except when the strain is re-moved. In brief, no exact idea of their adjustment can be got at any other pointexcept at the centers, and it is safe topresume that if the rods pass the centerseasily there is hardly any possibility ofdifficulty at any other point. When the brasses are closed in refit-ting it should be seen that the openingfor the oil way is sufficiently e
