Excerpt from The Pot-Culture House at the Agricultural Research Institute, Pusa The Cross-mil Trolly. - Two patterns of cross-rail trolly are employed in different Institutes. The one (which is also common to the French railway system) runs on a rail on the same level as the general system, and the trolly is itself above the general level. This pattern is used in the pot-culture House at the Woburn Agricultural Station in England. The other pattern runs on rails below the general level, and the top of the trolly comcides with this. This pattern is used at Pusa. In the first instance the cross-rail was 13 inches below the ground-level, but as this proved an inconvenience when stepping across it the axles were recently altered and the cross - rail raised to 6 inches from the ground-level as seen in Plate No. 4. It is indeed simple to con struct a trolly which does not require the cross-rail to be more than about 4 inches below the ground-level, and the less this depression, the more convenient for the pedestrian.
