Its commencement, like ordinary malaria, is generally announced by shivering fits, during which the sufferer experiences a sensation of extreme cold. The hands and feet are numbed and glacial; the teeth chatter continually, notwithstanding the fact that the thermometer in the verandah is often, in such cases, at 95 degrees. This is succeeded at the end of an hour or more by a feeling of burning heat; perspiration ceases, the sufferer's temperature rises to over a hundred; he is a victim of terrible pains in the head, and is often delirious. At Cho-Trang this condition was usually complicated by hematuric symptoms, which, fortunately, do not occur in the majority of cases of ordinary jungle fever.

There was no doctor in the fort (indeed, it would be impossible to maintain a medical officer in each of the numerous small garrisons in Tonquin), and it was the lieutenant who examined the sick men and served out the medicines provided by the authorities without stint.

In such cases commanders of forts are furnished with a manual, which is well written, and gives in the clearest of terms explanations concerning the symptoms and treatment of the different tropical and other diseases they will most probably be called upon to treat. Definite instructions are also given in this little book to the officers, concerning the transfer of the men to the nearest hospital centre, whenever there are signs that the disease from which they are suffering is of a persistent or malignant form. Though these recommendations are not always adhered to, it would hardly be fair in such cases to censure the commanders, since it often happens, on numerous removals of this kind being made, that the officer receives blame from headquarters for having neglected to take the necessary precautions to ensure the satisfactory sanitation of his post, whereas in most instances the epidemic has had its origin in the insanitary position of the fort, or the dangerous composition of the soil it was built on.

It was noticeable that the first among my comrades to fall victims to sickness were the younger members of the detachment. When they had a strong and healthy constitution they generally recovered, and though the fever clung to them for six months, and sometimes more, during which period the attacks gradually decreased in force and occurred at longer intervals, they eventually became seasoned, and the fever seemed no longer to have any hold on them. I know of a good many men who have served four consecutive years in the colony, and who, after paying a heavy toll to malaria, during the first year or eighteen months, have never again been troubled by the disease.

Hard drinkers were longer in resisting the attacks of the fever fiend, but once the illness got a hold upon them, the results were generally fatal. One of the peculiarities of the jungle fever, in any form, is that the sufferer loses all appetite; indeed, he usually exhibits almost a loathing for any kind of food. It is therefore necessary to maintain his vitality, which rapidly sinks under the repeated attacks of the disease. To obtain this result liberal allowances of liquid food are administered to the patient. In Tonquin, milk, either fresh or condensed, was the diet most frequently prescribed, and in most cases with excellent results, except when the sufferers happened to be confirmed alcoholic subjects. Then the patients would either refuse to take milk, for which they possessed a decided repugnance, or they would be unable to keep and digest it after having forced themselves to swallow it.

It is easy to understand that, owing to the number of men incapacitated through sickness, the duties of the few available for service were considerably increased. It was no unusual occurrence to find oneself detailed for guard three times in one week, and it was only by reducing things to their strictest limit that sufficient men could be found to escort the convoy which was brought from Bac-Lé every Thursday. The convoy was absolutely necessary, for we depended on this weekly service for our supply of food. A reserve stock of flour, wine, rice, coffee, sugar and salt, sufficient to feed the members of the garrison for three months, was stored in the fort; but this was only to be drawn upon in cases of extreme urgency, such as siege or blockade.

It was during this trying time that I was able to appreciate the good-fellowship and unobtrusive self-abnegation possessed by the majority of my comrades, and many instances of their kindly spirit came under my observation.

Whenever a man detailed for service fell sick shortly before going on duty—and this was by no means a rare occurrence—a chum would at once cheerfully volunteer and take his place, though, as often as not, he had himself just come off convoy or guard duty, or was recovering from an attack of fever.

The able men not on duty—they were generally but few—neglected their own comfort, and sacrificed their rare hours of rest to attend, without murmur, to their stricken comrades, and did their best, in their rough but kindly way, to lighten their sufferings.

It was a quaint and touching sight to watch one of these bearded mercenaries, as he passed from cot to cot, and note his efforts to repress his own impatience and clumsiness, as he piled blanket after blanket on a shivering sufferer, changed the damp linen of another, who had broken into the beneficent sweat that denoted the termination of an attack, or calmed, with a voice which he tried to render gentle, the ravings of a delirious friend, standing the while to change every few minutes the wet bandages on the burning brow of the stricken one.
