We would like to have any party who isinterested in a serviceable street pavement see this have done about all the street railroad track paving kinds of paving have been used in tracks, and I thinkit is conceded by all here that our block is the most suit-able material. We have tried various methods of join-ing the pavement to rails, and have demonstrated that the. USE OF FILLER, COLUMBUS, O. best plan is what we now use; namely, a brick linerin the groove of the rail as per sketch. The Johnsongirder rail is used, and by filling the grooves with thisbrick liner made to fit the groove and fill it out so as topresent a solid bearing for the end of the paving block tobutt against, the best results are obtained. The pre-vailing theory is that tracks are built so solid that theywill not move up and down, but the fact is, very fewtracks are built so perfectly solid that at some point therail does not move. This is especially true where elec-tric motor cars are used. There should, therefore, be ajoint between the rail and pavement so made that if therail moves it will not disturb the paving. At the sametime it should be the best possible joint if the rail doesnot move. Such we find this plan to be after trying agood many others.
