. The James way : a book showing how to build and equip a practical up to date dairy barn. Barns; Barns; Dairy barns; Dairy barns; Dairying. James Ventilators with Solid Hood Fig. 1 James Solid Hood Ventilator. Fig James Revolvmg H' specifically ordered, additional. These ventilators differ in principle from the James Ventilator with revolving hood only insofar as the inverted cone is substi- tuted for the revolving top. The ventilators without the revolving hood are, of course, somewhat less efficient be- cause the larger outlet space of the revolving head and the added motive power of suction obtained through the intensifier is not used. Nevertheless they are very efficient ventilators—more so than any other ventilator now on the market for dairy barns. They are built on strictly scientific principles, made of the same high quality materials and of the same class of workmanship as the James Ventilators with revolving hood. The inverted cone "A", Fig. I , turns the air rising from the outtake flues outward and upward. There is no opportunity for the outflow- ing current of air to turn back upon itself, cause eddies, choke the flue, or interfere in any way with the free escape of foul air. The storm band and the skirts keep out snow and rain and make the ventila- tor proof against the wind. All openings are protected by galvan- ized bird-proof netting. Ventilators Nos. 3 and 4, as shown in Fig. 4, page 290, are furnished with weather vane. The Ventilators with bases sho\vn in Figs. I , 2 and 3, will be furnished with weather vane if desired at an extra cost. Any of the six figures shown on page 292 may be selected. The cow figure will be furnished unless another style is Any name or date will be stenciled on a ventilator base lor $ entilator Size of James Ventilator to Buy Size 12" 18" 24" 30" WITHOUT REVOLVING HOOD Hogs 10 24 42 64 WITH REVOLVING HOOD 4 9 15 23 Horses 3 7 12 17 26 Horses 13 20 Hogs 72 Length of Building (Building
