All of these things had to be provided, and they were provided through a natural evolution of practical processes, crystallizing into form, tested by the duties of the day.

The organization which grew up was a true survival of the fittest, both in personnel and in methods.

The wonder is not that some abuses occurred, but that they were so few; not that there were occasional evidences of lack of efficiency, but that efficiency was on the whole so high from the beginning.
The several provinces were made administrative units, the commanding officer in each being designated as "senior inspector." The men who were to serve in a given province were by preference recruited there, and a departure was thus made from the usual foreign colonial practice.
In 1905 the total force was fixed at one hundred companies with a nominal strength of two officers and fifty men each.

Under special conditions this rule may be departed from, and the size of the companies or the number of officers increased.
Each province is divided by the senior inspector into sections, and the responsibility for patrol work and general policing rests on the senior company officer in each station.

The provinces are grouped into five districts, each commanded by an assistant chief who exercises therein the authority, and performs the duties appropriate to the chief for the entire Philippines.
