The new-comer had paid no least attention to his hostess, but sat down at the table and fingered the jumbles, apees, and cake known as "lovers'-knots" of Nanny's make, until he discovered one to his fancy. Mrs. Swanwick gave no obvious sign of annoyance, but smilingly stirred the chocolate, while Margaret quietly removed the dish of cakes and gave the guest a slice of sweetened bread known as "Dutch loaf."

"There are fewer currants in the cake than there were last week," remarked the astronomer, for, as Schmidt said in an aside to De Courval and Hamilton, as they watched the great eat like lesser folk: "This is the famous astronomer, David Rittenhouse. He divides his thoughts between the heavens and his diet; and what else there is of him is Jacobin."

"I wish," said Hamilton, "that heaven equally engaged the rest of his party. May not I have my chocolate, Mrs. Swanwick?"

"Certainly; and might I be noticed a little?" said Mrs. Swanwick to Rittenhouse. The absent-minded philosopher looked up and said:

"I forgot. Pardon me, Citess."

Hamilton laughed merrily. "Is that the last invention?"

"It sounds like the name of some wild little animal," said the Pearl.

"Neat, that, Margaret," said Hamilton; "and might I, too, have a peach? Mr. Jefferson has emptied the basket."

Margaret rose, and with De Courval went down the garden, a fair presentment of the sexes, seen and approved by Hamilton, while Jefferson said gaily:

"The transit of Venus, Rittenhouse," for it was that observation which had given this star-gazer fame and recognition abroad.
