In actual service, the volunteers will be valuable behind works; thus releasing a corresponding number of the regular troops from garrison service: but it cannot be too strongly impressed upon them, that unless they will submit to the necessary training as soldiers, and are complete in organization as infantry, no general in the world will have any confidence in them as a field force. The occasional embodiment of our volunteers at some of the great camps, as before recommended, would appear the most available means of training them for general service. It would also have another good effect, by demonstrating to many who are now carried away by their enthusiasm, how far they may be really calculated or prepared for the necessary trials and sacrifices incidental upon taking the field in the emergency. It will then be perceived by many that their age, want of physical stamina, or inability to dispense with habitual comforts which may be absolutely necessary to them, would render them totally unequal to the task they would willingly undertake. It would be far better that these should be weeded from the field corps of volunteers, and not remain to give a false appearance of their strength for actual service. Lastly, there may be some who, on reflection, must be aware that certain family ties, or private concerns, may imperatively forbid their joining the service at the last moment, and it would be far better that they should withdraw betimes from the engagement. For it should be borne in mind that these bodies are _volunteers_, in the strictest sense of the term; their presence or continuance in the field cannot be constrained. The effort to bear all the trials and hardships of a campaign requires a patience and endurance which will yield, even where there is thorough ardour in the cause, and great personal courage, unless supported by physical strength. The Volunteer Corps is a service in which the country must trust entirely to the honour of the individuals composing it; and certainly, those who shall stand the test will be peculiarly entitled to the gratitude of the nation.
