comes this because it is the
focus of the collectively enhanced emotion and sentiment of the group.
It becomes the representation and the symbol of what the crowd feels and
wills at the moment when all members are suffused with a common
collective excitement and dominated by a common and collective idea.
This excitement and this idea with the meanings that attach to it are
called collective because they are a product of the interactions of the
members of the crowd. They are not individual but corporate products.

Le Bon describes the organization thus effected in a chance-met
collection of individuals as a "collective mind," and refers to the
group, transitory and ephemeral though it be, as a "single being."

The positive factors in determining the organization of the crowd are
then:

(1) A condition of _rapport_ among the members of the group with a
certain amount of contagious excitement and heightened suggestibility
incident to it.

(2) A certain degree of mental isolation of the group following as a
consequence of the _rapport_ and sympathetic responsiveness of members
of the group.

(3) Focus of attention; and finally the consequent.

(4) Collective representation.

C. TYPES OF MASS MOVEMENTS

1. Crowd Excitements and Mass Movements: The Klondike Rush[308]

It was near the middle of July when the steamer _Excelsior_ arrived in
San Francisco from St. Michael's, on the west coast of Alaska, with
forty miners, having among them seven hundred and fifty thousand
dollars' worth of gold, brought down from the Klondike. When the bags
and cans and jars containing it had been emptied and the gold piled on
the counters of the establishment to which it was brought, no such sight
had been seen in San Francisco since the famous year of 1849.

On July 18 the _Portland_ arrived in Seattle, on Puget Sound, having on
board sixty-eight miners, who brought ashore bullion worth a million
dollars. The next day it was stated that these miners had in addition
enough gold concealed about their persons and in their baggage to double
the first estimate. Whether all these statements were correct or not
does not signify, for those were the reports that were spread throughout
the states. From this last source alone, the mint at San Francisco
received half a million dollars' worth of gold in one week, and it was
certain that men who had gone away poor had come back with fortunes. It
was stated that a poor blacksmith who had gone
