half" of a full day's employment "on some day other than Saturday" was to give the minimum duration of a half-holiday, not to prohibit one being taken on a Saturday. Children were not to be employed under the age of ten, and should attend school half-time until fourteen (or until thirteen if they had a good record of school attendance and satisfactory scholastic achievement). (In Scotland, for factory children only, this overrode attempts by local school boards to set standards of scholastic attainment to be met before a child could cease full-time schooling; the Scottish education acts ceded precedence to the factory acts. In England and Wales it was unclear whether factory acts or education acts had precedence until the Elementary Education Act of 1880 settled the matter in favour of school board bye-laws, but without any standardisation of criteria between different boards. Specification of a minimum educational attainment before a factory child could work half-time then became enforceable in England, but remained unenforceable in Scotland until passage of the Education (Scotland) Act 1883.) 'Half-time' could be achieved by splitting each day between school and work, or (unless the child worked in a domestic workshop) by working and attending school on alternate days. If the former, the child should work morning and afternoons on alternate weeks; if the latter the schooldays in one week should be workdays the next (and vice versa). No child should work a half-day on successive Saturdays. Surgeons no longer certified the apparent age of a child (or young person), age now being substantiated by a birth certificate or school register entry, but (for employment in factories) they were required to certify the fitness for the work of children and young persons under the age of sixteen. Protected persons should not be allowed to clean moving machinery, the requirement to guard machinery now extended to the protection of men as well as protected persons, and the Home Secretary might direct that some or all of the fine imposed for a breach of this requirement be paid to any person injured (or the relatives of any person killed) as a result. (Guarding was now only unnecessary if the position of machinery meant it was equally safe if unguarded, but hoists still only needed to be guarded if a person might pass close to them.) There were restrictions on the employment of some classes of protected persons on
