The Boston building trades strike which began yesterday has deprived the contractors for the Counting House and Lionel and Mower Halls of plumbers and lathers. Work on Massachusetts Hall will not be affected.

Progress at all three buildings will be only slightly impeded for the present, for by good fortune most of the plumbing has been put in, and the rest will be delayed. The carpenters have signed a three-year contract and will not strike unless there are unforeseen developments. The lathers have not yet worked on the buildings and will not be needed for some time.

Massachusetts In No Danger

Only a general strike of all trades could seriously retard the work in the interior of Massachusetts Hall. The completed exterior has been restored to its original appearance and two chimneys, lacking in the building which burned, have been erected on foundations provided in the original building.

In Lionel and Mower Halls and the Counting House the plumbing is not complete. A bricklayer's strike would retard Lionel Hall and a carpenters' strike would stop most work on all three buildings.

Discover Many Old Relics

Several discoveries of old relics have added interest to the construction work. In a number of the trenches which have been made, and even on the surface, old remains from former buildings have been found. An English penny, dated 1742, the year of the erection of Holden Chapel, was found several days ago by the foreman. Tony, close beside the chapel. A silver spoon of the pre-Revolutionary period was turned up by a spade yesterday. A host of other articles found during the excavating last fall have been retained and catalogued.
