It is, of course, true that the specialist tends to "go off at a tangent" on his particular subject, and even to treat with contempt or opposition the views of other specialists who differ from him. But all work that is worth doing is attended by its own peculiar dangers. It is here that the work of the non-specialist comes in. It is for him to compare the opposing views of the specialists, to reveal one in the light thrown by the other, to help into existence the new truth waiting to be born of the meeting of opposites. Specialisation spells division of labour, and apart from division of labour certain great work can never be done. To do away with such division, supposing an impossibility to be possible, would simply mean reversion to the state of the primitive savage. But we have no call to attempt the abolition of even the minutest division of labour. What is necessary is to understand and guard against its dangers. Specialisation _may_ lead to madness, as electricity _may_ lead to death. But no specialist need go far astray who, once in a while, will make an honest attempt to come to an understanding with the man whose views are diametrically opposed to his own. For thus he will retain elasticity of brain, and gain renewed energy for, and perhaps fresh light on, his own problems.--[EDS.] CAMPING OUT. IV. THE FIVE-FOOT SAUSAGE. The question of blankets and mattresses may be taken as settled. We can now sleep quite comfortably, take our fresh air sleeping and waking, and find shelter when it rains. But that same fresh air brings appetite and we must see how that appetite is to be appeased. Take a frying-pan. It should be of aluminium for lightness; though a good stout iron one will help you make good girdle-cakes, if you get it hot and drop the flour paste on it. You must find some other way of making girdle-cakes, and if you take an iron frying pan with you, don't say that I told you to. Though it is obviously necessary that a frying-pan should have a handle, I was bound to tell Gertrude that I do not find it convenient to take handled saucepans when I go camping. I take for all boiling purposes, including the making of tea, what is called a camp-kettle. Most ironmongers of any standing seem to keep it, and those who have it not in stock can show you an illustration of it in their wholesale list. It is just like the pot in which painters carry their paint, except that it has an ordinary saucepan lid. You should have a "nest" of these--that is, three in diminishing sizes going one inside the other. The big lid then fits on the outer one and the two other lids have to be carried separately.
