search. Enlighten his ignorance, that's a
good fellow."

"Enlighten him yourself, if you want to. You'll tell it all wrong:
but I'm tired," declared Foe.

"Well, then," said I, "it's this way, dear James. . . . You behold
seated opposite to you on the right of the fireplace, and smoking the
beast of a brier pipe with the modesty of true genius, a Scientific
Man--a Savant, shall I say?--of European reputation. It isn't quite
European just yet: but it's going to be, which is better."

"I always prophesied it," said Jimmy. "What's it going to be _for_?"

"Listen," said I. "Having received (as you assure us) a liberal
education, either at Eton or B.N.C., you probably made acquaintance
with that beautiful poem by Dr. Isaac Watts beginning--"

'Let dogs delight to bark and bite-'

"Continue the quotation, with brief notes on any obscurities."

"Certainly," said Jimmy.

'Let dogs delight to bark and bite,
'Tis manners so to do--'

"No, that sounds a bit off."

'Let dogs delight to bark and bite,
For God hath made them so;
Let bears and lions growl and fight,
For 'tis their nature toe.'

"Good boy!" said I. "Now that's where Dr. Watts--"

just getting into my stride--"

'But, children, you should never let
Such angry passions rise:
Your little hands were never made
To tear each other's eyes . . .'

"Please, I don't know any more."

"Nor need you," I assured him, "for, according to Jack, it's
completely out of date."

"'M'yes!" Jimmy agreed. "But he won't get a European reputation by
discovering _that_. They don't tear each other's eyes at the N.S.C.,
even--it's against the rules. Come and see for yourself, Professor."

"Angry passions," I went on patiently; "envy, hatred, and malice--
especially hatred--are Jack's special lay; the Grand Research we call
it. Take simple anger, for instance. What is it makes a man angry?"

"Lots of things. . . . Being called a liar, for one."

Foe took the mischief in the boy's eye, and let out a laugh.
"I can't be angry with _you_, anyway. Go on, Roddy. You're doing it
quite well so far, though I'm almost too sleepy to listen."

"It isn't as simple as you think," I pursued seriously (but glad
enough in my heart to have heard Jack laugh--he wasn't given to
laughter at any time). "All sorts of things happen inside you;
