With a Novena to the Holy Ghost and devotions for Mass, Holy Communion, etc. THE use of this book is fourfold: 1. It serves for short visits to Our Lord in the tabernacle. 2. It is designed to sene still better for long visits to the Blessed Sacrament. By means of it, half-hours and hours of adoration may be spent before the Tabernacle in the most fruitful and interesting manner; hence the sub-title has been affixed. It is indeed specially intended as a vade mecum for those pious souls who, as members of Eucharistic Leagues and Confraternities, are accustomed to keep the weekly or monthly Hour of Adoration. 3. It tends to inculcate and to foster devotion to the Holy Ghost, in connection with devotions to the Holy Eucharist. 4. It is finally a Prayer-Book for all ordinary occasions and devotions, especially for Mass and Holy Communion. Our little book follows the suggestions of Pere Eymard-the venerated and zealous Apostle of the Holy Eucharist- for making the hour of adoration. The pious adorer is never permitted to lose sight of the four ends of sacrifice or of the obligations we have to God, as our almighty Creator and supreme Master, viz.: 1. Adoration; 2. Thanksgiving; 3. Reparation; and 4. Prayer.
