Slatter’s Hill, or No-man’s-land, as it was generally called, was a rise of ground covering, perhaps, an acre and a quarter, situated on an imaginary line, marking the boundary between the two districts.  An immense stratum of granite, which here and there thrust out a wrinkled boulder, prevented the site from being used for building purposes.  The street ran on either side of the hill, from one part of which a quantity of rock had been removed to form the underpinning of the new jail.  This excavation made the approach from that point all but impossible, especially when the ragged ledges were a-glitter with ice.  You see what a spot it was for a snow-fort.

One evening twenty or thirty of the North-Enders quietly took possession of Slatter’s Hill, and threw up a strong line of breastworks, something after this shape:

The rear of the entrenchment, being protected by the quarry, was left open.  The walls were four feet high, and twenty-two inches thick, strengthened at the angles by stakes driven firmly into the ground.

Fancy the rage of the South-Enders the next day, when they spied our snowy citadel, with Jack Harris’s red silk pocket handkerchief floating defiantly from the flag-staff.

In less than an hour it was known all over town, in military circles at least, that the “Puddle-dockers” and the “River-rats” (these were the derisive sub-titles bestowed on our South-End foes) intended to attack the fort that Saturday afternoon.

At two o’clock all the fighting boys of the Temple Grammar School, and as many recruits as we could muster, lay behind the walls of Fort Slatter, with three hundred compact snowballs piled up in pyramids, awaiting the approach of the enemy.  The enemy was not slow in making his approach—­fifty strong, headed by one Mat Ames.  Our forces were under the command of General J. Harris.

Before the action commenced, a meeting was arranged between the rival commanders, who drew up and signed certain rules and regulations respecting the conduct of the battle.  As it was impossible for the North-Enders to occupy the fort permanently, it was stipulated that the South-Enders should assault it only on Wednesday and Saturday afternoons between the hours of two and six.  For them to take possession of the place at any other time was not to constitute a capture, but on the contrary was to be considered a dishonorable and cowardly act.

The North-Enders, on the other hand, agreed to give up the fort whenever ten of the storming party succeeded in obtaining at one time a footing on the parapet, and were able to hold the same for the space of two minutes.  Both sides were to abstain from putting pebbles into their snow-balls, nor was it permissible to use frozen ammunition.  A snow-ball soaked in water and left out to cool was a projectile which in previous years had been resorted to with disastrous results.

These preliminaries settled, the commanders retired to their respective corps.  The interview had taken place on the hillside between the opposing lines.
