"And you're as blind as a bat! Can't you see for yourself that Father and Mother have got some secret they're keeping from us? Why are we having our summer dresses made in April? Why are all our underclothes being overhauled and counted? Why did two new trunks arrive yesterday, with K. H. M. and G. C. M. painted on them in red letters? Why did Father just begin to say something last night, and Mother shut him up in a hurry, and he look conscience-stricken, and murmur: 'I'd forgotten they don't know yet'? Girl alive! if you're blind I'm not. There's something exciting on foot. I'm wild to find out what. Why doesn't Mother tell us? It's too bad." "She's just going to now," said a voice from the door, and a small, bright-eyed little lady walked in, laughing. "You shan't be kept in the dark any longer, poor injured creatures! I'll make a clean breast of it at last." "Mumsie!" cried both girls, jumping up, and sweeping away the books and painting materials that encumbered the one arm-chair. "Sit here, you darling! It isn't turpentiny, really! Here's the cushion. Are you comfy now? Well, do please begin and tell. We're all in a dither to know." "Brace your nerves then, chicks! First and foremost, Father has been asked in a hurry to go out to the Scientific Conference at Sydney, and give the lectures on Geology in place of Professor Baillie, who has been taken ill, and can't keep his engagement. He has accepted, and must start by the 28th. He wants me to go with him. We shall probably be away for three months." "And leave us!" Gwethyn's voice was reproachful. "Are we to be two sort of half orphans for three whole months? Oh, Mumsie!" "It can't be helped," replied Mrs. Marsden, stroking the brown head apologetically. "What a Mummie's baby you are still! Remember, it's a great honour for Father to be asked to take the Geology chair at the Conference. He's ever so pleased about it. And of course I must go too, because----" The girls smiled simultaneously, and with complete understanding. "If you weren't there to remind him, Mumsie, Daddie'd forget which days his lectures were on!" twinkled Katrine. "Yes, and I verily believe he'd put his coat on inside out, or wear two hats, or do something horrible, if he were thinking very hard of the Pleistocene period. He'd be utterly lost without you. No, you couldn't let him go alone!" "It's not to be thought of," agreed Mrs. Marsden hastily. "Pack Kattie and me inside your trunk," urged Gwethyn's beseeching voice. "I'd like to see Australia." "Too expensive a business for four. No, we've made other plans for you. Get up, Baby! You're too heavy to nurse. Go and sit somewhere else--yes, on the table, if you like. Well, Father and I have talked the matter thoroughly over, and we've decided to send you both for a term to a boarding-school we know of in Redlandshire."
