Philadelphia made a great mistake when she embraced over 2,000 acres in a single park, - which takes so much money that there is none left of any consequence for parks in other parts of her immense territory of 120 square miles. Even the small city squares are paragons of filth solely because after the great Fairmount Park, the taxpayers are not able to pay for more. There are thousands on thousands of Philadelphians who pay heavily for this park, who have never more than seen it, because it means a day's journey and a day's expenses. Boston, with its usual good sense, has been waiting to see what is best to be done, and will now profit by its sister's errors. They have nothing much to boast of as yet but the " Common," which after all is by no means to be despised as a pretty piece of garden work. Now the city is about to act. There are now waiting action before the City Councils orders for $600,000 for a park in West Roxbury; $100,000 for a marine park at City Point, South Boston; $200,000 for a park in Brighton; $300,000 for the Charles River Embankment, on the Back Bay toward Cambridge; $200,000 for the Muddy River improvement, and $50,000 for the East Boston Park.
