Arthur Clarke - The Deep Range

The scientist looked at his watch and muttered to himself, “Two minutes to go; she’s usually in sight by now.” He glanced out beyond the reef, then said with satisfaction, “Ah — there she is!”

A long black mound was moving in toward the island and a moment later Franklin saw the typical stubby spout of vapor which identified the humpback whale. Almost at once he saw a second, much smaller spout, and realized that he was watching a female and her calf. Without hesitation, both animals came in through the narrow channel that had been blasted through the coral years ago so that small boats could come up to the lab. They turned left into a large tidal pool that had not been here on Franklin’s last visit, and remained there waiting patiently like well-trained dogs.

Two lab technicians, wearing oilskins, were trundling something that looked like a fire extinguisher to the edge of the pool. Lundquist and Franklin hurried to join them, and it was soon obvious why the oilskins were necessary on this bright and cloudless day. Every time the whales spouted there was a miniature rainstorm, and Franklin was glad to borrow protection from the descending and nauseous spray.

Even a warden seldom saw a live whale at such close quarters, and under such ideal conditions. The mother was about fifty feet long, and, like all humpbacks, very massively built. She was no beauty, Franklin decided, and the large, irregular warts along the leading edges of her flippers did nothing to add to her appearance. The little calf was about twenty feet in length, and did not appear to be too happy in its confined quarters, for it was anxiously circling its stolid mother.

One of the scientists gave a curious, high-pitched shout, and at once the whale rolled over on her side, bringing half of her pleated belly out of the water. She did not seem to mind when a large rubber cup was placed over the now-exposed teat; indeed, she was obviously cooperating, for the meter on the collecting tank was recording an astonishing rate of flow.

“You know, of course,” explained Lundquist, “that the cows eject their milk under pressure, so that the calves can feed when the teats are submerged without getting water in their mouths. But when the calves are very young, the mother rolls over like this so that the baby can feed above water. It makes things a lot simpler for us.”

The obedient whale, without any instructions that Franklin could detect, had now circled round in her pen and was rolling over on the other side, so that her second teat could be milked. He looked at the meter; it now registered just under fifty gallons, and was still rising. The calf was obviously getting worried, or perhaps it had become excited by the milk that had accidentally spilled into the water. It made several attempts to bunt its mechanical rival out of the way, and had to be discouraged by a few sharp smacks.

Franklin was impressed, but not surprised. He knew that this was not the first time that whales had been milked, though he did not know that it could now be done with such neatness and dispatch. But where was it leading? Knowing Dr. Lundquist, he could guess.

“Now,” said the scientist, obviously hoping that the demonstration had made its desired impact, “we can get at least five hundred pounds of milk a day from a cow without interfering with the calf’s growth. And if we start breeding for milk as the farmers have done on land, we should be able to get a ton a day without any trouble. You think that’s a lot? I regard it as quite a modest target. After all, prize cattle have given over a hundred pounds of milk a day — and a whale weighs a good deal more than twenty times as much as a cow!”

Franklin did his best to interrupt the statistics.

“That’s all very well,” he said. “I don’t doubt your figures. And equally I don’t doubt that you can process the milk to remove that oily taste — yes, I’ve tried it, thanks. But how the devil are you going to round up all the cows in a herd — especially a herd that migrates ten thousand miles a year?”

“Oh, we’ve worked all that out. It’s partly a matter of training, and we’ve learned a lot getting Susan here to obey our underwater recordings. Have you ever been to a dairy farm and watched how the cows walk into the autolactor at milking time and walk out again — without a human being coming within miles of the place? And believe me, whales are a lot smarter and more easily trained than cows! I’ve sketched out the rough designs for a milk tanker that can deal with four whales at once, and could follow the herd as it migrates. In any case, now that we can control the plankton yield we can stop migration if we want to, and keep the whales in the tropics without them getting hungry. The whole thing’s quite practical, I assure you.”

Despite himself, Franklin was fascinated by the idea. It had been suggested, in some form or other, for many years, but Dr. Lundquist seemed to have been the first to do anything about it.

The mother whale and her still somewhat indignant calf had now set out to sea, and were soon spouting and diving noisily beyond the edge of the reef. As Franklin watched them go, he wondered if in a few years’ time he would see hundreds of the great beasts lined up obediently as they swam to the mobile milking plants, each delivering a ton of what was known to be one of the richest foods on earth. But it might remain only a dream; there would be countless practical problems to be faced, and what had been achieved on the laboratory scale with a single animal might prove out of the question in the sea.

“What I’d like you to do,” he said to Lundquist, “is to let me have a report showing what an — er — whale dairy would require in terms of equipment and personnel. Try to give costs wherever you can. And then estimate how much milk it could deliver, and what the processing plants would pay for that. Then we’ll have something definite to work on. At the moment it’s an interesting experiment, but no one can say if it has any practical application.”

Lundquist seemed slightly disappointed at Franklin’s lack of enthusiasm, but rapidly warmed up again as they walked away from the pool. If Franklin had thought that a little project like setting up a whale dairy had exhausted Lundquist’s powers of extrapolation, he was going to learn better.

“The next proposal I want to talk about,” began the scientist, “is still entirely in the planning stage. I know that one of our most serious problems is staff shortage, and I’ve been trying to think of ways in which we can improve efficiency by releasing men from routine jobs.”

“Surely that process has gone about as far as it can, short of making everything completely automatic? Anyway it’s less than a year since the last team of efficiency experts went over us.” (And, added Franklin to himself, the bureau isn’t quite back to normal yet.)

“My approach to the problem,” explained Lundquist, “is a little unconventional, and as an ex-warden yourself I think you’ll be particularly interested in it. As you know, it normally takes two or even three subs to round up a large school of whales; if a single sub tries it, they’ll scatter in all directions. Now this has often seemed to me a shocking waste of manpower and equipment, since all the thinking could be done by a single warden. He only needs his partners to make the right noises in the right places — something a machine could do just as well.”

“If you’re thinking of automatic slave subs,” said Franklin, “it’s been tried — and it didn’t work. A warden can’t handle two ships at once, let alone three.”

“I know all about that experiment,” answered Lundquist. “It could have been a success if they’d tackled it properly. But my idea is much more revolutionary. Tell me — does the name “sheep dog” mean anything to you?”
