Query: Surgery diagrams for horizontal contact structures   We describe Legendrian surgery diagrams for some horizontal contact
structures on non-positive plumbing trees of oriented circle bundles over
spheres with negative Euler numbers. As an application we determine Milnor
fillable contact structures on some Milnor fillable 3-manifolds.
