Then, again, with regard to the probable truth of the foregoing statement of the natives, perhaps I should call attention to the fact that the entire sum of seal-life in 1836, as given by them, is just four thousand one hundred, of all classes, distributed as I have indicated above. Now, on turning to Bishop Veniaminov, by whom was published the only statement of any kind in regard to the killing on these islands from 1817 to 1837 (the year when he finished his work), I find that he makes a record of slaughter of seals in the year 1836 of four thousand and fifty-two, which were killed and taken for their skins; but if the natives’ statements are right, then only fifty seals were left on the island for 1837, in which year, however, four thousand two hundred and twenty were again killed, according to the bishop’s table, and according to which there was also a steady increase in the size of this return from that date along up to 1850, when the Russians governed their catch by the market alone, always having more seals than they knew what to do with.
Again, in this connection, the natives say that until 1847 the practice on these islands was to kill indiscriminately both females and males for skins; but after this year, 1847, that strict respect now paid to the breeding-seals, and exemption of all females, was enforced for the first time, and has continued up to date.
In attempting to form an approximate conception of what the seals were or might have been in those early days, as they spread themselves over the hauling and breeding grounds of these remarkable islands, I have been thrown entirely upon the vague statements given to me by the natives and one or two of the first American pioneers in Alaska. The only Russian record which touches ever so lightly upon the subject[126] contains a remarkable statement which is, in the light of my surveys, simply ridiculous now—that is, that the number of fur-seals on St. George during the first years of Russian occupation was nearly as great as that on St. Paul. A most superficial examination of the geological character portrayed on the accompanying maps of those two islands will satisfy any unprejudiced mind as to the total error of such a statement. Why, a mere tithe only of the multitudes which repair to St. Paul in perfect comfort over the sixteen or twenty miles of splendid landing ground found thereon could visit St. George, when all of the coast-line fit for their reception on this island is a scant two and a half miles; but, for that matter, there was at the time of my arrival and in the beginning of my investigation a score of equally wild and incredible legends afloat in regard to the rookeries of St. Paul and St. George. Finding, therefore, that the whole work must be undertaken de novo, I went about it without further delay.
Thus it will be seen that there is, frankly stated, nothing that serves as a guide to a fair or even an approximate estimate as to the numbers of the fur-seals on these two islands, prior to the result of my labor.
At the close of my investigation during the first season of my work on the ground in 1872 the fact became evident that the breeding seals obeyed implicitly an imperative and instinctive natural law of distribution—a law recognized by each and every seal upon the rookeries prompted by a fine consciousness of necessity to its own well-being. The breeding-grounds occupied by them were, therefore, invariably covered by the seals in exact ratio, greater or less, as the area upon which they rested was larger or smaller. They always covered the ground evenly, never crowding in at one place here to scatter out there. The seals lie just as thickly together where the rookery is boundless in its eligible area to their rear and unoccupied by them as they do in the little strips which are abruptly cut off and narrowed by rocky walls behind. For instance, on a rod of ground under the face of bluffs which hem it in to the land from the sea there are just as many seals, no more and no less, as will be found on any other rod of rookery ground throughout the whole list, great and small—always exactly so many seals, under any and all circumstances, to a given area of breeding-ground. There are just as many cows, bulls, and pups on a square rod at Nah Speel, near the village, where in 1874, all told, there were only seven or eight thousand, as there are on any square rod at Northeast Point, where a million of them congregate.
This fact being determined, it is evident that just in proportion as the breeding-grounds of the fur-seal on these islands expand or contract in area from their present dimensions, so the seals will increase or diminish in number.
That discovery at the close of the season of 1872 of this law of distribution gave me at once the clue I was searching for, in order to take steps by which I could arrive at a sound conclusion as to the entire number of seals herding on the Pribylov group.
I noticed, and time has confirmed my observation, that the period for taking these boundaries of the rookeries, so as to show this exact margin of expansion at the week of its greatest volume, or when they are as full as they are to be for the season, is between July 10th and 20th of every year—not a day earlier and not many days later. After July 20th the regular system of compact, even organization, breaks up. The seals then scatter out in pods or clusters, the pups leading the way, straying far back: the same number then instantly cover twice and thrice as much ground as they did the day or week before, when they laid in solid masses and were marshalled on the rookery ground proper.
There is no more difficulty in surveying these seal-margins during this week or ten days in July than there is in drawing sights along and around the curbs of a stone fence surrounding a field. The breeding-seals remain perfectly quiet under your eyes all over the rookery and almost within your touch, everywhere on the outside of their territory that you may stand or walk. The margins of massed life, which are indicated on the topographical surveys of these breeding-grounds of St. Paul and St. George, are as clean cut and as well defined against the soil and vegetation as is the shading on my maps. There is not the least difficulty in making such surveys, and in making them correctly.
Without following such a system of enumeration, persons may look over these swarming myriads between Southwest Point and Novastoshnah, guessing vaguely and wildly, at any figure from one million up to ten or twelve millions, as has been done repeatedly. How few people know what a million really is! It is very easy to talk of a million, but it is a tedious task to count it off: this makes a statement as to “millions” decidedly more conservative when the labor has been accomplished. After a thorough survey of all these great areas of reproduction the following presentation of the actual number of seals massed upon St. Paul is a fair one:
