Angularily rather far……….. to one view but I don't quite see [illeg] of Agassiz saying as surface Rocks are angular & are therefore remains of the lateral moraines.

c…. subsequently removed; or not deposited, former more probable – I almost assume polishing & scratching of surfaces of the granites, then [illeg] & interior valleys only difficulty – There is phenomenon to be explained admitted by Agassiz, which [eroding] glacier will not explain – gravel or sand only [part] absolutely farmable & no new ferruginous only slow rise & submersion of Jura
