Floating with the peculiar lightness which distinguishes the gull tribe, the birds seemed to occupy almost every yard of water.
"You spoke of collecting the eggs," said Dick to the keeper; "what do you do with them?"
"Oh, we sell them for eating. They are as good as plovers' eggs. I can get one shilling and sixpence or two shillings a score here for them, and the men who buy them of me get a good profit in Norwich market."
"How many eggs do you get?"
"Oh, that depends upon whether it is a good year or a bad one. In a good year we take 12,000 eggs or more. This year we have had one take already of 2,500 in one day, and I expect to get about 1,500 to-day. You see my men are collecting already. We only take the first laying of each bird if we can help it, but nests are so close together that it is hard to remember which we have taken and which we have not. If you would like to come on the Hearth, as we call the island in the middle, you can do so, but you must put these mud boards on your feet, for it is very soft and dangerous walking."
Common Gull.
They crossed to the island in a heavy tub of a boat, and were surprised to see the number of eggs and nests. The nests were not more than one yard apart, built on the ground like water-hens', but not so cup-shaped. The number of eggs seemed to be about three in each nest, and their colour was generally olive brown, blotched and spotted with darker brown, but there was a very great variety in their colour. Some were very light, some were very dark, and others were all blue like a heron's egg. The business of collecting the eggs went on very quietly and expeditiously, but the boys were almost made dizzy with the constant swooping of the gulls about their heads, and almost deafened by their cries. One part of the marshy island was so soft that no one could walk upon it, and the gulls which bred there never had their nests disturbed except by the rats and weasels, which naturally abound in such places.
