The hypothesis of evolution supposes that in all this vast progression there would be no breach of continuity, no point at which we could say, "This is a natural process," and "This is not a natural process," but that the whole might be compared to that wonderful process of development which may be seen going on every day under our eyes, in virtue of which there arises, out of the semifluid, comparatively homogeneous substance which we call an egg, the complicated organization of one of the higher animals. That, in a few words, is what is meant by the hypothesis of evolution.[10]
Here Huxley has laid out, in compact form the principal ramifications of the great principle of evolution, giving his hearers something like an outline map of it with its limits and principal divisions.
Where you have a practice or system to define, you will be more likely to do it by specifying the chief and essential details of the system, as in the following definition of commission government for cities. It will be noticed that this narrows down the meaning of the term to something like the Des Moines system, as distinguished from the Galveston plan.
A straight commission form of municipal government, in the judgment of Dr. Charles W. Eliot, one of its most active advocates, requires a commission composed of five members elected at large, one of whom is called the mayor, acting as chairman of the commission, but with no veto power, or any other special power not shared by the other members of the commission.
The commission so elected is the source of all authority in the city, makes all ordinances, appoints all officials, collects taxes, and makes all appropriations. As set forth by its advocates, the significant features of the plan, in addition to those already mentioned, are:
Assignment of the important divisions of the city government to individual members of the commission, or their election thereto by the voters, each being directly responsible for the conduct of his particular department; adequate compensation to the commissioners for their time and labor, the city employing all the commissioners at living salaries, thus elevating the dignity of municipal service and making it a public career, and not a mere avocation; regularity, frequency, and publicity of the meetings of the commissioners; all employees above the class of day laborers selected from eligible lists based on examinations, oral and written, carefully devised to develop merit and fitness; recommendations after examination by an independent civil service commission; provision for the retention in office of all employees so appointed during good behavior; the power to initiate legislation reserved to the people, this right being known as the initiative; the power to call for a public vote on any measure adopted by the commission before being given effect as law reserved to the people, this being known as the referendum; the power at any time to make any member of the commission stand for reelection reserved to the people, this being known as the recall; the granting of public franchise always to be submitted to the approval of the electors.
