Another English student of labor conditions declares: "Teachers--together with magistrates, police authorities, ministers of religion and social workers--are practically unanimous in condemning street trading as an employment of children of school age. In this occupation children deteriorate rapidly from the physical, mental and moral point of view."[96] Still another writer says: "One great evil which results from this life of street trading in childhood is the fact that it is fatal to industrial efficiency in after life."[97] The testimony of Sir Lauder Brunton, M.D., given in 1904, on the occasion of the inquiry into physical deterioration in Great Britain, is to the point, in spite of the fact that the committee directing the inquiry stated that "The impressions gathered from the great majority of the witnesses examined do not support the belief that there is any general progressive deterioration."[98] Sir Lauder Brunton's testimony was as follows: "The causes of deficient physique are very numerous ... it is very likely that in order to eke out the scanty earnings of the father and mother the child is sent, out of school hours, to earn a penny or two, and so it comes to school wearied out in body by having had to work early in the morning, exhausted by not having had food, and then is sent to learn. Well, it cannot learn."[99] Later the same witness testified, "One of the very worst causes [of physical deterioration] is that children in actual attendance at school, work before and after schooltime."[100]
