The transfer of Roebuck's two-third interest to Boulton afterward
carried with it the formation of the celebrated firm of Boulton and
Watt. The latter arranged his affairs as quickly as possible. He had
only made $1,000 for a whole year spent in surveying, and part of that
he gave to Roebuck in his necessity, "so that I can barely support
myself and keep untouched the small sum I have allotted for my visit to
you." (Watt to Small, July 25, 1773). This is pitiable indeed--Watt
pressed for money to pay his way to Birmingham upon important business.

The trial engine was shipped from Kinneil to Soho and Watt arrived in
May, 1774, in Birmingham. Here a new life opened before him, still
enveloped in clouds, but we may please ourselves by believing that
through these the wearied and harassed inventor did not fail to catch
alluring visions of the sun. Let us hope he remembered the words of the
beautiful hymn he had no doubt often sung in his youth:

"Ye fearful saints, fresh courage take
The clouds ye so much dread
Are big with mercy, and shall break
With blessings on your head."

Partnership requires not duplicates, but opposites--a union of different
qualities. He who proves indispensable as a partner to one man might be
wholly useless, or even injurious, to another. Generals Grant and
Sherman needed very different chiefs of staff. One secret of Napoleon's
success arose from his being free to make his own appointments, choosing
the men who had the qualities which supplemented his and cured his own
shortcomings, for every man has shortcomings. The universal genius who
can manage all himself has yet to appear. Only one with the genius to
recognise others of different genius and harness them to his own car can
approach the "universal." It is a case of different but cooperating
abilities, each part of the complicated machine fitting into its right
place, and there performing its duty without jarring.

Never were two men more "supplementary" to each other than Boulton and
Watt, and hence their success. One possessed in perfection the qualities
the other lacked. Smiles sums this up so finely that we must quote him:

Different though their characters were in most respects, Boulton
at once conceived a hearty liking for him. The one displayed in
perfection precisely those qualities which the other wanted.
Boulton was a man of ardent and generous temperament, bold
