THE ELM PROBLEM.

Now that Boston has been smitten in respect to the okas on the Common interest in the problem of shade trees has been aroused anew. Some method of supplying beautiful and useful shade-trees must be found at once.

Accordingly, the suggestion from Paris seems especially pertinent. To supplant the dead trees with mature full-grown trees is, briefly, the plan. The necessity of enduring a collection of ambitious but ineffective saplings while they try with dubious success to grow into trees is thus obviated. The period, necessarily of considerable length, between the time when the old trees begin to die and the time when other trees of healthy maturity appear to replace them is reduced to a minimum as is the risk of failure.

The expense of the process is somewhat greater than reforestation by the use of saplings but the reward justifies it, and the apparent success of the Paris method warrants a trial.
