Toreduce the declivities of these roads to say five feet in onehundred would in many cases require complete re-location ofthe ways. In some cases the projects can be so contrived thatthe steep grade can be reduced by short detours without effect-ing the general plan of the ways. In a word, it seems wise forthe present to limit the work of improvement mainly to theexisting lines of road, accepting in the process the routes asthey exist, except where it is expedient to insist on the widen-ing of the location. MA SSA CHUSE TTS HIGH WA Y COMMISSION. 81. Rolling the Second Course. SHADE TREES. The Commission is directed, when feasible, to plant treesalong the State highway. It is impossible with the presentdata to estimate the cost of planting and maintaining shadetrees along State highways. From crude estimates based onpresent information, the ultimate cost of such work may be onemillion dollars. It seems doubtful to the Commission, withthis limited knowledge, whether it would be advisable toattempt the planting of shade trees during the coming Commission has taken much advice from experts concern-ing the best varieties of trees for planting, and has had observa-tions made in the climatic and soil divisions of the State as tothe species \\Tiich have proved most successful by the wayside. It has been suggested that elms, both American and Englishare so subject to the attack of insects that their protection fromthese pests would prove too costly, and also for the reason thattheir roots, extending as they do for a
