A few sport clubs exist, also under the control of the corps, but they do not play a very prominent part, for the taste for athletic exercises is confined to a small minority. Considering the small number of players, the proficiency attained in the exotic games of football and hockey is surprisingly high. The rowing is even better, and attracts a larger number, being perhaps more suited to the physical characteristics of the race than those games for which agility is more necessary than weight and strength. Boat-races are held annually between the several Universities, in which the form of the crews is generally very good. If I am not mistaken, some of the Dutch crews that have rowed at Henley represented University clubs. The typical student, however, though well enough endowed with bone and muscle, has no ambition whatever to become an athlete, or to submit to the fatigue and self-denial of training. Probably the way he lives and his aversion to athletics, more than the length of his course of study, account for his elderly appearance, for he is not only obviously older than the average undergraduate, but begins to look positively middle-aged both in face and figure almost before he has done growing. Before leaving the subject of the students' corps, mention must be made of the great carnival which each corps holds every five years to commemorate the foundation of its University. The 'Lustrum-Maskerade,' which is the chief item in the week of festivities, is a historical pageant representing some event in the mediæval history of Holland. The chief actors are chosen from among the wealthiest of the students, and spare no trouble or expense in preparing their get-up, while the minor parts are allotted to the various clubs within the corps, each club representing a company of retainers or men-at-arms in the service of one of the mock princes or knights. For six days the players retain their gorgeous costumes and act their parts, even when excursions are made in the neighbourhood in company with the friends and relatives who come to join in the commemoration, and the mixture of mediæval and modern costumes in the streets has a somewhat ludicrous effect. On the first day the visitors are formally welcomed by the officers of the corps. Former students of all ages meet their old comrades, and the men of each year, after dining together, march together to the garden or park where the reception is held. Anything less like the usual calm and serious demeanour of these seniors than the way in which they dance and sing through the town is not to be imagined, for the oldest and most sedate of them are as wildly and ludicrously enthusiastic as the youngest student; and their arrival at the reception, with bands of music, skipping about and roaring student songs like their sons and grandsons, is, to say the least, comical. But the occasion only comes once in five years, and they naturally make the most of it.
