Curiously enough, this border-line between black and white showed considerable variations in individuals and even on both sides of one animal's body. I welcomed this, since it enabled me to recognize my shrews personally.

Three days after their arrival in Altenberg my eight shrew babies opened their eyes and began, very cautiously, to explore the precincts of their nest-box. It was now time to remove them to an appropriate container, and on this question I expended much hard thinking. The enormous quantity of food they consumed and, consequently, of excrement they produced, made it impossible to keep them in an ordinary aquarium whose water, within a day, would have become a stinking brew. Adequate sanitation was imperative for particular reasons; in ducks, grebes and all water-fowl, the plumage must be kept perfectly dry if the animal is to remain in a state of health, and the same premise may reasonably be expected to hold good of the shrew's fur. Now water which has been polluted soon turns strongly alkaline and this I knew to be very bad for the plumage of water-birds. It causes saponification of the fat to which the feathers owe their waterproof quality, and the bird becomes thoroughly wet and is unable to stay on the water. I hold the record, as far as I know hitherto unbroken by any other bird-lover, for having kept dabchicks alive and healthy in captivity for nearly two years, and even then they did not die but escaped, and may still be living. My experience with these birds proved the absolute necessity of keeping the water perfectly clean; whenever it became a little dirty I noticed their feathers beginning to get wet, a danger which they anxiously tried to counteract by constantly preening themselves. I had, therefore, to keep these little grebes in crystal-clear water which was changed every day, and I rightly assumed that the same would be necessary for my water-shrews.
