At night-time the prisoners are supposed to sleep in jail—an ordinary native house set apart for this purpose—but at the present time in Murray Island, owing to the absence of a jail, they sleep at home! and during the whole of the time they are under the surveillance of one or more policemen. Very often it appeared to me that a policeman’s chief duty consisted in watching a prisoner doing nothing. Very bad, or often repeated, offenders are taken to Thursday Island to be tried by the Resident Magistrate.
CHAPTER III
WORK AND PLAY IN MURRAY ISLAND
The first thing we did after arranging the house was to convert a little room into a dispensary, and very soon numbers of natives came to get medicine and advice. McDougall, Myers, and Seligmann worked hard at this, partly because they were really interested in the various cases, and partly since it brought natives to the house who could be utilised for our other investigations.
The doctors also paid visits to bad cases in their homes. As the former white missionaries on the island in days gone by had been accustomed to dispense, to the best of their ability, from their somewhat large assortment of drugs, the natives took it for granted that we should do the same; hence there were no special signs of gratitude on their part. Bruce, too, does what he can for the natives, but his remedies are naturally of a simple, though often drastic, character.
The medical skill and gratuitous advice and drugs of our doctors did a great deal to facilitate the work of the expedition. Towards the end of our time, hearing Captain H⸺ of Darnley Island was seriously ill, McDougall volunteered to go over and nurse him, and he remained there for a week or two.
It was a great safeguard for us, too, having so many doctors about; but fortunately we only required their aid, or they each other’s, for malarial fever or for minor ailments like sores. Only on three occasions during the time we were away, till we left Borneo, were there sufficiently bad cases of fever to cause the least anxiety. So, on the whole, we came off remarkably well on the score of health.
Although we have a fair amount of information about the external appearance, the shape of the head, and such-like data of most of the races of mankind, very little indeed is known about the keenness of their senses and those other matters that constitute the subject commonly known as experimental psychology. My colleagues were the first thoroughly to investigate primitive people in their own country, and it was the first time that a well-equipped psychological laboratory had been established among a people scarcely a generation removed from perfect savagery.
Dr. Rivers undertook the organisation of this department, and there were great searchings of heart as to what apparatus to take out and which to leave behind. There was no previous experience to go upon, and there was the fear of delicate apparatus failing at the critical time, or that the natives would not be amenable to all that might be required of them. Fortunately the latter fear was groundless. It was only in the most tedious operations, or in those in which they were palpably below the average, that the natives exhibited a strong disinclination to be experimented upon. Sometimes they required a little careful handling—always patience and tact were necessary, but taking them as a whole, it would be difficult to find a set of people upon whom more reliable and satisfactory observations could be made. I refer more particularly to the Torres Straits islanders.
In his work in Murray Island, Rivers was assisted by Myers and McDougall. During his trips to New Guinea, Seligmann made some supplemental observations of interest. The subjects investigated included visual acuity, sensitiveness to light, colour vision, including colour blindness, binocular vision, and visual space perception; acuity and range of hearing; appreciation of differences of tone and rhythm; tactile acuity and localisation; sensibility to pain; estimation of weight, smell, and taste; simple reaction times to auditory and visual stimuli, and choice reaction times; estimation of intervals of time; memory; strength of grasp and accuracy of aim; reading, writing, and drawing; the influence of various mental states on blood-pressure, and the influence of fatigue and practice on mental work.
