Samples Nos. 2 & 3: Two short lengths of 5" Pipe which burst after being laid.
From a cursory examination of these three samples, I beg to offer the following remarks:-

This 6" Pipe had apparently not been in use, as the screwed end is referred to as having 'torn off' when an attempt was made to lay the Pipe". It is difficult to understand how this breakage occurred, and I can only conjecture that the screwed end was subjected to an undue strain in process of laying, such as would happen if several lengths of Pipe were connected up on the ground, and then lowered into the trench without proper precaution being taken to see that no irregular stress was put upon any of the Pipes. I would say that it would be impossible to
