“What a funny custom!” exclaimed Nettie, again.

The only building they visited was the Church of St. Lawrence, where they saw the famous great organ, a splendid structure, larger than the great organs of Haarlem and Boston. It is one hundred and fifty feet high, mounted upon a colonnade fifty feet high, and has five thousand five hundred pipes.

In the market-place they saw a statue of the great scholar Erasmus, and “the house where he was born,” which is now, alas! a gin-shop. From the Boomptjes, a fine quay, planted with rows of beautiful trees, and surrounded by elegant, dark brick mansions, our party chartered a little sail boat, and went out upon the Maas.

The beautiful, quiet Maas, with Rotterdam’s green, woody banks in view; the blue, blue sky, seen clearly in the limpid waters; the steamers coming and going, and birds flying around, adding their sweet notes to nature’s harmony—this beautiful picture was one remembered by the children all their lives. To-morrow’s parting hung its shadow over them, and softened their hearts to the true beauty everywhere expressed.

The sun had set when they reached the Vyverberg for the last time.

“Mamma,” said Eric, regretfully, “I almost wish I was going home with you all.”

“Uncle Charlie may come to-night,” said his mother, cheerfully. “At any rate, he will soon come. You would then wish you had staid.”

“Yes, I know,” said Eric. “But it is very hard to let you all go home without me, for all that.”

Very careful directions were given to Eric, and he was placed under the care of the landlord until he should hear from his uncle.

The evening was very short to Eric, who lingered by his mother, and could not bear to leave her side, knowing he should see her no more for a long, long year.
