Conditions could be much worse; and as far as my employers are concerned — well, they realise that we are experimenting with a new method of cleaning gas, and if this experience costs them twenty thousand dollars, they can stand it.

情况可能会更糟；就我的雇主而言——好吧，他们意识到我们正在试验一种清洁气体的新方法，如果这种体验要花费他们两万美元，他们也能承受。
