The City of Prestonsburg is merely a conduit through which the board of education acts to have the bonds issued and sold. The city has no discretion in the matter and it was properly required to lend its cooperation to the agreement proposed by the board of the independent district. Fyfe v. Hardin County Board of Education, 305 Ky. 589, 205 S.W.2d 165; Franklin County v. Franklin County Board of Education, 267 Ky. 554, 102 S.W.2d 1024; Carter v. Taylor, 313 Ky. 445, 231 S.W.2d 601; Hopkins County Fiscal Court v. Commonwealth, Ky., 252 S.W.2d 875. It is likewise clear that the validity of the bonds will not be affected by the merger.
