Summary 'It sifts from Leaden Sieves' by Emily Dickinson is a beautiful poem that focuses on the striking ability of snow to obscure the world. Throughout the stanzas of 'If sifts from Leaden Sieves,' the poet depicts snow as something that falls, as flour does through a sieve, onto the earth gently. It's a beautiful and noteworthy sight that the speaker spends a great deal of time ...
