the hot closet; and what is collected 

 there will not be so easily radiated 

 through the tin as through the black 

 sheet iron. 



An Egg-clock which shall ring a bell, 

 or set off an alarm, at any number of 

 minutes that may be required, is formed 

 by a dial like that of a watch, but larger, 

 surmounted by an alarm-bell, and with 

 five divisions, representing five minutes 

 on the dial. This being fixed up over the 

 kitchen fireplace, all that is necessary is 

 to move the index to the number of 

 minutes the egg is to be boiled. While 

 the boiling is going on, the cook or 

 attendant may be employed in doing 

 other work till the alarm goes off. The 

 act of moving the index or pointer back- 

 wards winds up this clock. The prin- 

 ciple might be applied to a larger dial, 

 so as to mark the time requisite for cooking articles generally ; and we have ac- 

 cordingly engaged a brass-founder to undertake such an apparatus. We feel 

 confident that it will be found a most valuable addition to the kitchen furniture, 

 both of the poor and rich, by allowing the ordinary work of the kitchen to go 

 on without the interruption occasioned by watching, &c. Even the boiling of 

 an egg occasions some loss of time, in watching the clock or sand-glass. 



Schools. — At Belper and Milford there are schools in which the whole po- 

 pulation employed in the manufactories are educated at a moderate rate, and 

 both chapels and churches at which they may attend. As we have said before, 

 however, this is a subject which we cannot enter on at present, and must 

 content ourselves with expressing our admiration at the order displayed at 

 these factories ; it is highly gratifying, because it shows what may be done, 

 and what, no doubt, will be done, when public opinion (much more effective 

 than legislation in cases of this kind) is powerfully directed to the detection 

 of inhumanity in manufacturing establishments. 



The Residence of Joseph Strutt, Esq., in Derby. — In a gardening point of view, 

 the hot-house is worthy of note for its movable front sashes, which admit of ex- 

 posing the vines to the open air in the winter season, and at the same time keep- 

 ing them dry, as first described in the Horticultural Trans., and subsequently in 

 the Encyclopcedia of Gardening (see edit. 1835, p. 783.), and in Vol. VII. p. 41 1. 

 of this Magazine. We first saw this vinery in November, 1826 ; and then, 

 as now, both vines and pines were doing well. The vine borders are not 

 cropped, and in winter they are thatched in such a manner as to carry off 

 the rain and melted snow to a drain of between 20 ft. and 30 ft. distant from 

 the front glass. In the stove there are some well-grown Orchidaceae and 

 other hot-house plants. Against the wall of the dwelling-house, there is an 

 ^ristolochia sipho, one of the shoots of which we measured, and found up- 

 wards of 50 ft. in length. In the house there is a large collection of pictures 

 distributed through all the different rooms and staircases, but more particu- 

 larly in a handsome gallery, remarkably well lighted from the roof through 

 double sashes set at an oblique angle, the inner sashes being of ground 

 glass, to soften the rays of the sun. It is heated by hot air, and also by 

 small tubes filled with hot water ; which, however, are only used during 

 the most severe cold. The outer sashes in the roof protect the inner ones 

 from dust, and also prevent the escape of heat during winter, and its entrance 

 during summer. There are two ventilators in the upper part of the roof 

 of the skylights, which are opaque. This gallery, like every other part of 

 the house, is lighted by gas ; and, taking into account the lighting by day 

 and by night, the warming and the ventilation, it is one of the most com- 

 plete picture galleries that we know of. In consequence of the double roof,
