a scavenger’s cart happening to stand unattended at the corner, with its little ladder planted against the wheel, Mr S. found it impossible to resist the temptation of shooting Mr Silas Wegg into the cart’s contents. A somewhat difficult feat, achieved with great dexterity, and with a prodigious splash.
Silas has to deal with the shame and humiliation of returning right back to the social position he tried so hard to escape and this interaction is great moment of symbolism. He is treated and throw out like a piece of trash into a scavenger’s cart, which is filled with literal garbage. This symbolizes how his social position in life will always prevent him from rising in any way and the last line of this paragraph encompasses that downfall perfectly.
