**today I leave for 3 weeks at Ottawa as guest lecturer in geology an environmental science. It's such a beautiful morning I regret going back into winter! [Betty now takes over this journal as follows:] We hada smaller egg today, indicating that our new J. J. Warren hens are laying eggs. Swanny Swan probably laid it because of her rather large comb. She's the one with the large comb and feathers evenly distributed about her body. In this figure it shows the difference in size between eggs [a drawing shows the new egg wit a greatest dimension of 3" and a 5" circumference and, for comparison, an average egg with greatest dimension of 2. 25 " and a cicumference of 6".]. 22 eggs today.
