 0 THI CONDOR. Vol. XXI The writer has often met in the layman's mind, a tendency to read into the behavior of lower animals the impulses of the human brain. Further still, some would impose upon the lower animal the restrictions of the Mosaic Law. In case the human law have no foundation in biologic law, is there any reason why it should be imposed upon the lower animal ? On the other hand, let us examine some of the laws of human ethics and see if they are merely different ways of stating laws of nature. I have already used in the preceding pages of this now too long article the words ' ' reprehensible' ', "recalcitrant' ', and "va- grant", but is it proper to do so? I maintain that the ethics which demands that the marital tie shall last "till death do us part" should not be imposed in those words upon the bird but that the same law, recast in terms of biology, is applicable to, and is observed by, a multitude of bird species. Let that law read thus: "The male and female shall coSperate during the period of the young's dependency upon parental care." Will it not work out for humans in the majority of cases, almost as well as does the ritual ? Take two biologic humans, uninfluenced by the artificial conditions of our later civilization. They establish the marital tie at the age of twenty years. The first offspring is born within the year and becomes independent at the age of eighteen or twenty. In the meantime there have appeared, at intervals of two years, other offspring to the number of ten. Is this an exaggeration for the bologic human family ? By the time the last young is independent, the parents have lived in active coSperation for the period of forty years, and have reached the age of'sixty. They had best not attempt any readjustment at that age, even Lhough they have no grandchildren on their hands. The ethical law is really a biologic law and we didn't know it. Apply the same restriction to the bird and you have a cooperative period not extending, as a rule, beyond the spring and summer of each single year, and sometimes for even less time than that. There is no biologic demand for a greater prolongation of the marital tie. Certainly there is nothing in the birds' code of ethics. Why hold to a human letterin of the law ?

TAVERNER WITH ONE PHOTO H AZELTON, BRITISH COLUMBIA, is at the head of the Skeena liver, at the forks where the stream is formed by the junction of the Bulkley and Babine rivers. It is the most northern point reached by the Grand Trunk Pacific lailroad, hence, with the exception of points on the new Hud- son Bay lailroad, it is the most northern station reached by any of the main railway systems in America. In latitude 55 20', it is on line with the mouth of James Bay and slightly north of Hamilton Inlet on the Labrador coast.
