We doubt whether our labours to accomplish either of the objects of this publication, if ever so successful, could produce such complete mitigation (rather abolition) of animal suffering as the substitution of locomotive machinery for the inhuman, merciless treatment of horses in our stage-coaches. The man who started the first steam-carriage was the greatest benefactor to the cause of humanity the world ever had. But in a political view the subject is very important. We have a superabundant population with a very limited territory, while each horse requires a greater quantity of land than would be sufficient to support a man. How extensive then would be the beneficial effect of withdrawing two-thirds of the horses and appropriating the land required for them to the rearing of cattle and to agricultural produce? The Liverpool and Manchester steam-coaches have driven fourteen horse-coaches off the road. Each of the horse-coaches employed twelve horses--there being three stages, and a change of four horses each stage. The total horses employed by these coaches was therefore 168. Now each horse consumes, on an average, in pasture, hay, and corn, annually, the produce of one and a half acre. The whole would thus consume the produce of 252 acres. Suppose, therefore, "every man had his acre" upon which to rear his family, which some politicians have deemed sufficient, the maintenance of 252 families is gained to the country by these steam-coaches. The average number in families is six, that is, four children, besides the father and mother.--The subsistence of 1,512 individuals is thus attained. * * * * * [Illustration: DIALLING.] (_For the Mirror._) The following method of constructing a dial, may be novel and interesting to many of those readers of the _Mirror_ who are fond of that ancient art; whilst its simplicity and the great ease with which it may be constructed, will render it acceptable to all.
