"Accounts for those accusing notes we've been getting from the Bureau of Fisheries. This poisonous dust is being carried out into Chesapeake Bay and is killing the fish."
Manning turned to Karst. "Do you think that possible, Doctor?"
I could see her brows draw together through the window in her helmet. "I hadn't thought about it," she admitted. "I'd have to do some figuring on the possible concentrations before I could give you a definite answer. But it is possible — yes. However," she added anxiously, "it would be simple enough to divert this drain to a sink hole of some sort."
"Hm-m-m — yes." He did not say anything for some minutes, simply stood there, looking at the box.
Presently he said, "This dust is pretty lethal?"
"Quite lethal, Colonel." There was another long silence.
At last I gathered he had made up his mind about something for he said decisively, "I am going to see to it that you get Obre's assistance, Doctor—"
"Oh, good!"
"— but I want you to help me in return. I am very much interested in this research of yours, but I want it carried on with a little broader scope. I want you to investigate for maxima both in period and intensity as well as for minima. I want you to drop the strictly utilitarian approach and make an exhaustive research along lines which we will work out in greater detail later."
She started to say something but he cut in ahead of her. "A really thorough program of research should prove more helpful in the long run to your original purpose than a more narrow one. And I shall make it my business to expedite every possible facility for such a research. I think we may turn up a number of interesting things."
