The writer has repeatedly suggested the use^ in addition, of mild artificial heat applied in a judicious manner, as, in his experience, it ap- peared to be a powerful factor in inducing early ovipositing by the queen and its prolongation during the autumn. I shall not deal here, however, with this subject again, as I intend later on to show the practical possibilites of artificial heat and how use could be made of it to revolutionise some of our present methods of bee culture, as soon as industrial con- ditions permit. One of your correspon- dents agreed to the value of artificial heat in the nursing of sick bees, but most of your readers do not even realise this point, and nearly all of them are under a misconception as to what I actually mean. BROOD HATCHING CHAMBER. by the utilisation of artificial heat. For this reason a reconsideration of this sub- ject (with some illustrations, if need be) at a future opportunity might be advan- tageous. I propose here to show by a simple in- expensive method how to intensify brood rearing, as distinct from inducing its com- mencement or prolonging it. This method necessitates the employment of a second brood chamber, which might be called, from its primary function, " the brood- hatching chamber," and depends on the utilisation of the natural warmth of the hive, as distinct from any artificial aid. The same natural heat could be utilised for artificial queen-hatching, independent of the attendance of any bees, but I do not propose here to examine the possible utility of this free source of useful heat. I was led to consider this subject seri- ously from reviewing the fact that, onc» the brood has been capped over, it is no longer in need
