The book first illustrates the value of period annuals through contemporary drawings and technical articles. Its Bullfinch account reconstructs the fatal 1899 machinery failure after a high-pressure connecting rod broke during a high-speed trial. Eleven men died in the steam-filled engine room, while the surviving engineer escaped by staying low and reaching a ladder. The analysis explains why hot steam collected overhead and why quickly reversing loads were more punishing than a simple static calculation suggested. Investigators could not isolate one cause, instead dividing responsibility among steel quality, rod geometry, weight-saving choices, and the stresses of nearly four hundred revolutions per minute.

Brassey's 1900 records the Bullfinch machinery disaster in engineering detail
A period account follows a destroyer's failed connecting rod, lethal steam escape, rescue work, and unresolved debate over material versus design fault.
